Synergistic Y-Doping Strategy To Simultaneously Enhance Sensing Response and Humidity Stability in NiO-Based Triethylamine Sensors

Jiaqi Yang, Yi Wang Chen, Yongjie Zhang, Wenjiang Han et autres

Developing MOS-based chemiresistors with both high gas response and humidity resistance poses challenges, primarily due to the effects of water-induced surface poisoning. To address this issue, Y ions are utilized as a beneficial modifying component on p-type NiO nanofibers for constructing a …

LITES-based methane isotope ratio measurement and source attribution

Jialiang Dai, Bing Luo, Haofeng Zhang, Wei Xiao et autres

This work presents what we believe to be the first application of light-induced thermoelastic spectroscopy (LITES) to methane isotope detection, demonstrating the development of a compact, low-power system. By targeting the near-infrared absorption lines of the two isotopologues 13 CH 4 and …

High-Efficiency Deep Ultraviolet Light-Emitting Diodes without an Electron Blocking Layer Enabled by a High-Aluminum-Content Spanning Superlattice p-Type Region

Xien Sang, Aoxiang Zhang, Xin Wang, Weiguang Ma et autres

Deep ultraviolet light-emitting diodes (DUV-LEDs) face critical challenges such as poor hole injection and significant electron leakage, both of which severely limit their external quantum efficiency (EQE). This study possesses and simulates six DUV-LED structures featuring p-type superlattices with varying aluminum compositions …

Optimizing Laser Diode Performance with Al-Composition Graded Last Quantum Barriers

Xin Wang, Weiguang Ma, Xien Sang, Fang Wang et autres

In this study, the effect of a linearly increasing Al composition in the last quantum barrier (LQB) on deep ultraviolet (DUV) laser diode (LD) was investigated. Simulation results show that, compared to traditional quantum barriers (QBs) with a constant Al composition, DUV …
