Chemical modification and vertical stacking of two-dimensional materials are promising techniques for new nanoelectronic devices. We present Density Functional Tight Binding(DFTB) calculations of a field-effect device...
With support from the National Natural Science Foundation of China and the Top 1000-Talents Awards,the research team led by Dr.Zheng HaiYan(郑海燕)and Dr.Li Kuo(李阔)from the Center for High Pressure Science and Techn...
We analyze the graphane p-n junction performance. The analysis method is based on solving Poisson and current equations by using the Green function method. The Green function method gives a simple and fast tool for so...
The present analytical review is devoted to the current problem of thermodynamic stability and related thermodynamic characteristics of the following graphene layers systems: 1) double-side hydrogenated graphene of co...
