This presentation will give an overview of the current status and future opportunities for high-frequency ultrawide bandgap (UWBG) semiconductor transistors. GaN-based transistors have demonstrated excellent performance for RF applications, but are close to the limits set by their electronic properties in the mm-wave regime. UWBG semiconductors such as high Al-content AlGaN can provide significantly higher breakdown electric field while having electron saturated velocity similar to GaN, and can in principle provide significant improvements in power-gain product at mm-wave frequencies. However, key challenges in real devices such as high contact resistance, premature breakdown of metal-semiconductor and dielectric interfaces, and thermal management must be addressed before such improved performance is realized. © 2022 IEEE.

Computational modeling and optimization were utilized to design the metastructure of a polymer nanocomposite system. The goal is to minimize the reflection loss (RL) and broaden the absorption bandwidth. Truncated cones with a perfect electric conductor on the top surface were chosen. With this innovative metastructure, the absorption bandwidth of RL at -20dB has been increased from 0, as observed in non-porous materials, to 1.83 GHz. The samples with optimized metastructures were manufactured using hot pressing and computer numerical control (CNC) machining techniques. This approach provided an efficient way to design and precisely manufacture materials with targeted EM absorption. © 2024 IEEE.

In this paper, we propose a novel approach to IR sensing using a narrow band gap semiconductor and the light-induced barrier lowering (LIBL) mechanism. Lead sulfide quantum dots (PbS QDs) were used as the semiconductor material due to their ideal bandgap energy for IR sensing. The proposed TFT sensor structures with and without a gap between gate and drain were fabricated and demonstrated excellent sensitivity to IR radiation, and therefore providing a cost-effective and accessible solution for IR sensing, with potential applications in various fields. © 2023, John Wiley and Sons Inc.

Supercapacitors are known for longer cycle life and faster charging rate compared to batteries. However, the energy density of supercapacitors requires improvement to expand their application space. To raise the energy density of redox supercapacitors, this work demonstrates electro-polymerization on both sides of electrodes to increase material loading, reduce overall device mass, and consequently increase the capacitance, power, and energy density of supercapacitors. We achieved an energy density of 1823 mWh kg-1 and a power density of 16.5 W kg-1 with a wide potential window of 3 V. © 2023 IEEE.

The methodology used is based on design thinking principles and takes advantage of the benefits of cloud computing. These include, but are not limited to, scalability, reliability, and security. The result is a solution that is not only powerful but also cost-effective. The core of this application follows a user-centered design philosophy and involves potential users closely in the design process. A comprehensive evaluation is performed using the System Usability Scale (SUS) methodology to measure the effectiveness and usability of the application. The results of this comprehensive approach are convincing. The application has an impressive 95.5% usage rate, indicating strong user engagement. Furthermore, user satisfaction ratings are particularly high and transformative impact of this application in a complex environment of legal harmonization. Through its innovative design, seamless functionality, and user-centric approach, this application has proven to be not only a technical solution, but also a catalyst for positive change in the legal and regulatory harmonization process. © 2023 IEEE.
