Nanocrystalline metal oxide thin films offer toxic gas sensing with higher sensitivity at lower
temperature compared to their bulk counter parts leading to miniaturization of the sensors …

Semiconductor materials with wide bandgaps are extensively employed for gas detection
due to their advantages of low cost, high sensitivity, fast speed, excellent stability, and …

Room temperature gas sensors have been widely explored in gas sensor technology for
real-time applications. However, humidity has found to affect the room temperature sensing …

Monitoring and reducing NO 2 pollution at room temperature is indispensable for human
survival. Thus, we propose a light-activated route (UV light, 100 mW/cm 2) to realize a high …

In this article, the adsorption of NO x (x= 1, 2) gas molecules on the (001) surface of
CoFeMnSi quaternary Heusler alloys has been investigated theoretically with density …

A selective NO 2 gas sensor was fabricated using Au-decorated ZnO nanofibers. A layer of
Au was sputter-deposited on the synthesized ZnO nanofibers. The thicknesses of the Au …

The prevalence of nitrogen dioxide (NO 2) in the atmosphere is causing a steady increase in
air pollution. As such, there is an urgent need to create a sensitive and energy-efficient NO 2 …

Gas sensors play a pivotal role in environmental monitoring, with NO2 sensors standing out
due to their exceptional selectivity and sensitivity. Yet, a prevalent challenge remains: the …

Abstract Bismuth sulfide (Bi2S3) is a promising candidate as nitrogen dioxide (NO2) gas
sensor due to it high sensitivity and mechanical stability. To investigate atomic-scale gases …

DFT-based calculations were undertaken to, first, fully optimize and study the structural and
electrical properties of bare BP nanowire (NW) in its hexagonal wurtzite (WZ) phase. The …
