Stacking patterns and carrier mobilities of GeS bilayer

Fazel Shojaei; Hong Seok Kang

Volume 9, Issue 3 , March 2018, , Pages 205-210


  Based on the first-principles calculations, we identify four stacking patterns of the GeS bilayer, in which two most stable ones are almost equally stable. The most stable one corresponds to the experimental pattern in bulk GeS.  Its interlayer binding is stronger than those in a-phosphorene and ...  Read More
