The field of 2D materials has gained a lot of attention for vast range of applications. Amongst others, the sensing ability towards harmful gases is the application, which we explored in the present work using quantum-mechanical simulations for the SnP3 material. Its electronic properties, namely 1 and 2 layers being semiconducting, while multilayers being metallic, offer a possibility to build a single-material logical junction. In addition, the harmful gases studied here show physical adsorption with charge transfer from the substrate to the gas molecules. Calculated recovery times show promise of a good sensing material. The I-V characteristics calculated for all cases indicates that SnP3 could be a viable sensing material towards NO gas via negative differential resistance.
