Serious climate changes and energy-related environmental problems are currently critical issues in the world. In order to reduce carbon emissions and save our environment, renewable energy harvesting technologies will serve as a key solution in the near future. Among them, triboelectric nanogenerators (TENGs), which is one of the most promising mechanical energy harvesters by means of contact electrification phenomenon, are explosively developing due to abundant wasting mechanical energy sources and a number of superior advantages in a wide availability and selection of materials, relatively simple device configurations, and low-cost processing. Significant experimental and theoretical efforts have been achieved toward understanding fundamental behaviors and a wide range of demonstrations since its report in 2012. As a result, considerable technological advancement has been exhibited and it advances the timeline of achievement in the proposed roadmap. Now, the technology has reached the stage of prototype development with verification of performance beyond the lab scale environment toward its commercialization. In this review, distinguished authors in the world worked together to summarize the state of the art in theory, materials, devices, systems, circuits, and applications in TENG fields. The great research achievements of researchers in this field around the world over the past decade are expected to play a major role in coming to fruition of unexpectedly accelerated technological advances over the next decade. © 2023 The Authors.

Compressed sensing based channel estimation for fast fading OFDM systems

Chinese Journal of systems Engineering and Electronics 2010年第4期000卷

A compressed sensing (CS) based channel estima-tion algorithm is proposed by using the delay-Doppler sparsity of the fast fading channel. A compressive basis expansion chan-nel model with sparsity in both time and frequency domains is given. The pilots in accordance with a novel random pilot ma-trix in both time and frequency domains are sent to measure the delay-Doppler sparsity channel. The relatively nonzero channel coefficients are tracked by random pilots at a sampling rate signifi-cantly below the Nyquist rate. The sparsity channels are estimated from a very limited number of channel measurements by the basis pursuit algorithm. The proposed algorithm can effectively improve the channel estimation performance when the number of pilot sym-bols is reduced with improvement of throughput efficiency.

Stabilizing ordering instead of randomness in alloy semiconductor materials is a powerful means to change their physical properties. We used scanning tunneling and transmission electron microscopies to reveal the existence of an unrecognized ordering in ternary III-V materials. The lazarevicite short-range order, found in the shell of InAs1−xSbx nanowires, is driven by the strong Sb-Sb repulsion along 〈110〉 atomic chains during their incorporation on unreconstructed {110} sidewalls. Its spontaneous formation under group-III-rich conditions of growth offers the prospect to broaden the limited classes of ordered structures occurring in III-V semiconductor alloys.

The Effects of surface pretreatments of p-GaN using H2SO4, HF, KOH solution on the optical and electrical properties of GZO/p-GaN contacts have been investigated using a rf magnetron sputter deposition. The current-voltage characteristics of GZO/p-GaN contact is slightly improved using KOH solution treatment. Contact barrier of GZO/p-GaN can be considerably reduced on annealing at 530 °C for 15 min in N2 ambient and the ohmic contact is almost achieved for with KOH-treated sample. the light luminance of 86.7 cd/m2 at current of 20 mA is obtained for GZO electrodes of LEDs with KOH pretreatment.

Aluminum nitride (AlN) film is a promising material which is used in various fields. In this study, AlN films with different plasma powers were grown by remote plasma atomic layer deposition. Saturation experiments have been applied in the plasma power between 1000 and 3000 W. The influence of plasma power on preferential orientation, chemical, optical, and electrical properties of AlN films are investigated. AlN films displayed multiphase hexagonal wurtzite crystal structure with (002) preferential orientation for higher plasma power, while the predominant orientation shifted toward (100) at lower plasma power. The optical emission spectroscopy analyses show that NH and NH2 radicals conduce to the deposition of AlN films and H radicals selectively dissociate Al-OH bonds which were on AlN film surface and etch deposition films. AFM measurements show that the 1500 W prepared AlN film with smallest surface roughness may be related to the relatively smaller concomitant crystal grains of (100) and (002). X-ray photoelectron spectroscopy investigation presents that oxygen content decreases as the plasma power increases. The obtained maximum value of dielectric constant and breakdown electrical field of AlN film deposited at 3000 W is 8.23 and 5.42 MV/cm, respectively. © 2023, The Authors. All rights reserved.

Advances in controllable growth of ultrathin two-dimensional molecular crystals (2DMCs) or even monolayer molecular crystals (MMCs) propelled their application in high-performance, high-sensitivity, low-contact-resistance optoelectronic devices. However, the rational molecular design strategies for materials prone to grow into ultrathin 2DMC or MMC have rarely been addressed. Here, systematically tailoring the π -conjugation and alkyl chain types of asymmetric anthracene derivatives, 2DMCs and even MMCs were obtained under the synergetic regulation of inter- and intralayer interactions. High-quality MMCs were obtained for SAP-C6 by traditional physical vapor transport technique (PVT), and corresponding organic field-effect transistors (OFETs) exhibited high mobility of 3.22 cm 2 V -1 s -1 . In addition, band-like charge transport with low activation energy was achieved by SAP-C6 MMC-OFETs. Furthermore, the SAP-C6 MMC-based device exhibits excellent thermal stability, retaining ∼70% of its initial performance at 140°C in air, which is the first report on the thermal stability of MMC devices. This research highlights the potential of alkyl-substituted asymmetric molecules as a design strategy to achieve ultrathin 2DMC or MMC growth, and improve the mobility and thermal stability in OFETs.
