In the "Beyond Moore's Law" era, with increasing edge intelligence, domain-specific computing embracing unconventional approaches will become increasingly prevalent. At the same time, adopting a variety of nanotechnologies will offer benefits in energy cost, computational speed, reduced footprint, cyber resilience, and processing power. The time is ripe for a roadmap for unconventional computing with nanotechnologies to guide future research, and this collection aims to fill that need. The authors provide a comprehensive roadmap for neuromorphic computing using electron spins, memristive devices, two-dimensional nanomaterials, nanomagnets, and various dynamical systems. They also address other paradigms such as Ising machines, Bayesian inference engines, probabilistic computing with p-bits, processing in memory, quantum memories and algorithms, computing with skyrmions and spin waves, and brain-inspired computing for incremental learning and problem-solving in severely resource-constrained environments. These approaches have advantages over traditional Boolean computing based on von Neumann architecture. As the computational requirements for artificial intelligence grow 50 times faster than Moore's Law for electronics, more unconventional approaches to computing and signal processing will appear on the horizon, and this roadmap will help identify future needs and challenges. In a very fertile field, experts in the field aim to present some of the dominant and most promising technologies for unconventional computing that will be around for some time to come. Within a holistic approach, the goal is to provide pathways for solidifying the field and guiding future impactful discoveries. © 2023, CC BY-NC-SA.

MRS Internet Journal of Nitride Semiconductor Research 2020年第1期5卷 514-520页

作者： Zhou, L. Khan, F. Ping, A.T. Osinsk, A. Adesida, I. Microelectronics Laboratory Department of Electrical and Computer Engineering Univ. of Illinois Urbana-Champaign U.S.A. NZ Applied Technologies Woburn U.S.A.

Ti/Pt/Au metallization on p-type GaN/AlxGa1−xN (x=0.10 and 0.20) superlattices (SL) were investigated as ohmic contacts. Current-voltage and specific contact resistance measurements indicate enhanced p-type doping in the superlattice structures compared to that in GaN. Ti/Pt/Au is shown to be an effective ohmic metallization scheme on p-type GaN/AlxGa1−xN superlattices. A specific contact resistance of Rc = 4.6×10−4 Ω-cm2 is achieved for unalloyed Ti/Pt/Au on GaN/Al0.2Ga0.8N SL. This is reduced to 1.3×10−4 Ω-cm2 after annealing for 5 minutes at 300 °C.

In the age of digitalization, data protection plays an important role. Data is created, modified and shared over the Internet between data owners and data users. A key issue in this context is the respect of data sovereignty. The International Data Spaces (IDS) Reference Architecture has been developed in order to preserve data sovereignty. In this regard, Internet of Things (IoT) devices, such as sensors, play an important role for providing data. However, an IoT device is not capable of being integrated directly into the IDS by default. We propose an approach to enable the IDS for vendor independent IoT devices, using an open interoperability standard for the IoT specified by the Open Geospatial Consortium (OGC). This allows data owners to benefit from providing their own data while retaining control over it.

The report presents approach to reduce PCB distortion after heat treatment for soldering using a reflow process. The influence of the temperature profile at different heating of the lower side of the board has been studied and an optimal one has been established, in which the distortion of the boards is minimal and there is no danger of creating defects on the lower side. Conclusions are made when this approach can be used and how a secure temperature profile can be achieved for minimal board distortion after soldering with a reflow process. © 2020 IEEE.

Superconducting Microstrip Losses at Microwave and Submillimeter Wavelengths

We present a lab-on-chip experiment to accurately measure losses of superconducting microstrip lines at microwave and submillimeter wavelengths. The microstrips are fabricated from Nb−Ti−N, which is deposited using reactive magnetron sputtering, and amorphous silicon which is deposited using plasma-enhanced chemical vapor deposition (PECVD). Submillimeter wave losses are measured using on-chip Fabry-Perot resonators (FPRs) operating around 350 GHz. Microwave losses are measured using shunted half-wave resonators with an identical geometry and fabricated on the same chip. We measure a loss tangent of the amorphous silicon at single-photon energies of tan δ=3.7±0.5×10−5 at approximately 6GHz and tan δ=2.1±0.1×10−4 at 350 GHz. These results represent very low losses for deposited dielectrics, but the submillimeter wave losses are significantly higher than the microwave losses, which cannot be understood using the standard two-level system loss model.

Low-Complexity Channel Estimation for RIS-Assisted ISAC System

arXiv

引用

arXiv 2025年

作者： Zhen, Chen Jianqing, Li Haijun, Zhang Wei, Zhang The Institute of Microelectronics University of Macau China School of Computer Science and Engineering Macau University of Science and Technology China Beijing Engineering and Technology Research Center for Convergence Networks and Ubiquitous Services University of Science and Technology Beijing Beijing China Henan Academy of Science Applied Physics Institute Co.Ltd Henan Zhengzhou China

Integrated sensing and communication (ISAC), assisted by reconfigurable intelligent surface (RIS) has emerged as a breakthrough technology to improve the capacity and reliability of 6G wireless network. However, a significant challenge in RIS-ISAC systems is the acquisition of channel state information (CSI), largely due to co-channel interference, which hinders meeting the required reliability standards. To address this issue, a minimax-concave penalty (MCP)based CSI refinement scheme is proposed. This approach utilizes an element-grouping strategy to jointly estimate the ISAC channel and the RIS phase shift matrix. Unlike previous methods, our scheme exploits the inherent sparsity in RIS-assisted ISAC channels to reduce training overhead, and the near-optimal solution is derived for our studied RIS-ISAC scheme. The effectiveness of the element-grouping strategy is validated through simulation experiments, demonstrating superior channel estimation results when compared to existing benchmarks.

We investigate the variations of circuit parameters of photovoltaic (PV) cells containing self-assembled InSb and GaSb quantum dots. The solar cell samples are fabricated by conventional molecular beam epitaxy on (0 0 1) GaAs substrate. The current–voltage ( I-V ) characteristics and the frequency response (10 Hz – 100 kHz) of the fabricated cell is then extracted in dark and illuminated environment. The obtained I-V curves show typical PV properties. The static series and shunt resistances can be then extracted from this measurement result. From the Nyquist plot of the device impedance, both dynamic resistance and capacitance can be further extracted. Variations of these values are quantified. Light-induced lowering of the resistance values are explained by the presence of photogenerated carriers. This work provides a useful information for both the basic understanding of PV devices and the design of electronic circuit for energy harvesting and sensing with PV cells.

Magnetic resonance spectroscopy (MRS) is an important clinical imaging method for diagnosis of diseases. MRS spectrum is used to observe the signal intensity of metabolites or further infer their concentrations. Although the magnetic resonance vendors commonly provide basic functions of spectra plots and metabolite quantification, the widespread clinical research of MRS is still limited due to the lack of easy-to-use processing software or platform. To address this issue, we have developed CloudBrain-MRS, a cloud-based online platform that provides powerful hardware and advanced algorithms. The platform can be accessed simply through a web browser, without the need of any program installation on the user side. CloudBrain-MRS also integrates the classic LCModel and advanced artificial intelligence algorithms and supports batch preprocessing, quantification, and analysis of MRS data from different vendors. Additionally, the platform offers useful functions: 1) Automatically statistical analysis to find biomarkers for diseases;2) Consistency verification between the classic and artificial intelligence quantification algorithms;3) Colorful three-dimensional visualization for easy observation of individual metabolite spectrum. Last, both healthy and mild cognitive impairment patient data are used to demonstrate the functions of the platform. To the best of our knowledge, this is the first cloud computing platform for in vivo MRS with artificial intelligence processing. We have shared our cloud platform at MRSHub, providing free access and service for two years. Please visit https://***/software_all/#CloudBrain-MRS or https://***/***. Copyright © 2023, The Authors.

Due to the fact that every smart building is a unique composition of devices, services, and users there is no one-fits-all security architecture. With our proposal we address this problem by using Building Information Modeling (BIM) as source of information for our security concept. Using BIM, models are created throughout the planning of a building, which do not consist only of 3D information such as typical CAD drawings, but also provide a rich set of metadata about the building elements including devices, their interrelationships and networking. Thus, BIM can be used to derive security configurations for each individual embedded device, its services and the network as a whole. We demonstrate the function of a general Security Controller to partition the network on MAC layer. Furthermore, we draw an overall picture of the proposed architecture and the range of possible applications.
