摘要:

在这项工作中,我们调查的堆叠顺序在二硫化钼多层系统上的电子输运性能的影响,通过第一性原理模拟的结构和电子输运性能。我们发现,层间电子输运是高度敏感的堆叠序列的多层膜,与特定的序列产生更高的电子传输由于较大的轨道相互作用和能带结构的影响。这些结果解释了对比实验证据层间传输测量由于不完善的结构控制,提供洞察建模和建议的方法来提高电子器件的性能的基础上,通过多层结构工程的二硫化钼多层系统。

英文摘要:

In this work, we investigate the effect of the stacking sequence in MoS2 multilayer systems on their electron transport properties, through first-principles simulations of structural and electron transport properties. We show that interlayer electron transport is highly sensitive to the stacking sequence of the multilayers, with specific sequences producing much higher electron transmission due to larger orbital interactions and band structure effects. These results explain contrasting experimental evidence on interlayer transport measurements as due to imperfect structural control, provide insight on modeling and suggest ways to improve the performance of electron devices based on MoS2 multilayer systems via multilayer structure engineering.
