Insights into Cold Source MOSFETs with Sub-60 mV/decade and Negative Differential Resistance Effect
Yiheng Yin, Zhaofu Zhang, Chen Shao +2
To extend the Moores law in the 5 nm node, a large number of two dimensional (2D) materials and devices have been thoroughly researched, among which the cold metals 2H MS2 (M = Nb,…
Schottky Barrier Heights of Defect-free Metal/ZnO, CdO, MgO and SrO Interfaces
Jiaqi Chen, Zhaofu Zhang, Yuzheng Guo +1
The Schottky barrier heights (SBHs) of defect-free interfaces of ZnO, CdO, MgO and SrO with various metals and different terminations are investigated by density functional superce…
Electronic Structure of Amorphous Copper Iodide: A p-type Transparent Semiconductor
Zhaofu Zhang, Yuzheng Guo, John Robertson
The atomic and electronic structure of the p-type transparent amorphous semiconductor CuI is calculated by ab-initio molecular dynamics. It is found to consist of a random tetrahed…
Transfer doping of Graphene by Species of Extreme Work Function
Haichang Lu, Yuzheng Guo, John Robertson
Density functional calculations are used to explain the charge transfer doping mechanism by which species physisorptively bonded to graphene can increase its free hole or electron…
Band Structure, Band Offsets, Substitutional Doping, and Schottky Barriers in InSe
Yuzheng Guo, John Robertson
We present a comprehensive study of the electronic structure of the layered semiconductor InSe using density functional theory. We calculate the band structure of the monolayer and…
Metal Insulator Transition of Cr doped V2O3 calculated by hybrid density functional
Yuzheng Guo, Stewart J. Clark, John Robertson
The electronic structure of vanadium sesquioxide in its different phases has been calculated using the screened exchange (sX) hybrid functional. The hybrid functional reproduces th…
