Stacking and electric field effects on the electronic properties of the layered GaN
Dongwei Xu, Haiying He, Ravindra Pandey +1
Stability and electronic properties of atomic layers of GaN are investigated in the framework of the van der Waals-density functional theory. We find that the ground state of the l…

Disorder induced field effect transistor in bilayer and trilayer graphene
Dongwei Xu, Haiwen Liu, Vincent Sacksteder +4
We propose use of disorder to produce a field effect transistor (FET) in biased bilayer and trilayer graphene. Modulation of the bias voltage can produce large variations in the co…

Phase Structure of the Topological Anderson Insulator
Dongwei Xu, Junjie Qi, Jie Liu +3
We study the disordered topological Anderson insulator in a 2-D (square not strip) geometry. We first report the phase diagram of finite systems and then study the evolution of pha…
