与石墨烯类似,硅烯应用于高表现场效应晶体管的关键在于:在保持高迁移率的前提下打开一个大的带隙.基于密度泛函理论,我们发现:单面吸附碱金属原子的方法可以有效的破坏硅烯的对称性,从而打开带隙.

This paper studies a periodic driven diffusive system,which separates into two equal‐sized parts with different values of hopping rates.Competition of the two different driven parts leads to various b
Efficient spin-polarized current injection into a nonmagnetic semiconductor is very crucial for the realization of spintronic devices.One of the main problems in spin injection is the impedance mismat
