摘要:

2D材料领域因其广泛的应用而备受关注。其中,对有害气体的传感能力是应用,我们在本工作中使用SnP 3材料的量子力学模拟进行了探索。它的电子特性,即1层和2层是半导体的,而多层是金属的,提供了建立单一材料逻辑结的可能性。此外,这里研究的有害气体显示出物理吸附与电荷转移从基板的气体分子。计算的恢复时间显示出良好的传感材料的前景。所有情况下计算的I-V特性表明,SnP 3可以是一个可行的敏感材料,通过对NO气体的负微分电阻。

英文摘要:

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.
