Abstract:
Theoretical design based on first-principles calculations play an important role in the discovery and innovational research of 2D materials. Recently, our group has proposed a series of novel 2D electronic, magnetic and optoelectronic materials: (1) 2D semiconductor with high carrier mobility including monolayer delta-Cu2S and eighteen monolayer oxides; (2) monolayer group-III monochalcogenides by oxygen functionalization as 2D topological insulators; (3) functionalized SbAs monolayers as spin–valley-coupled Dirac semimetals; (4) monolayer MnB, CrSCl and CrSeBr as 2D ferromagnets with high Curie temperature.
