Detection of Gas Molecules (CO, CO2, NO, and NO2) Using Indium Nitride Nanoribbons for Sensing Device Applications

The article investigates the electronic properties and structural stability of pristine, bare and several adsorption gases of ZInNNR-2, ZInNNR-4, and ZInNNR-6 structures. Density functional theory (DFT) is utilized to analyze the width dependency. It is demonstrated by the band structures and density of states (DOS) that the electronic properties of all bare ZInNNR structures have a metallic characteristic. Bare-ZInNNR-6 and Pristine-6 structures were found to be the most thermostatically stable based on binding energy computation and based on adsorption calculations, CO, CO2, NO, NO2 ZInNNR with a width of 6 were found to be the most energetically favorable configurations among all other ZInNNR-related configurations. Of all the evaluated ZInNNR configurations, the NO2/NO ZInNNR demonstrates the greatest selectivity, making it the preferred option for this application. The CO2-ZInNNR-6 configuration shows strong candidature to become the disposal sensing device due to its quicker recovery time. The suggested device demonstrates the superior sensing capability for nanoscale sensing devices.

Automated summary

This article investigates the electronic properties and structural stability of ZInNNR structures, as well as the effects of adsorption gases. The results show that bare ZInNNR structures have metallic characteristics, and bare-ZInNNR-6 and Pristine-6 structures are the most thermostatically stable. Among the adsorption gases, CO, CO2, NO, and NO2 show the highest energetically favorable configurations when adsorbed by ZInNNR-6.
