Realization of Room-Temperature Phonon-limited Carrier Transport in Monolayer MoS2 by Dielectric and Carrier Screening
Zhihao Yu, Zhun-Yong Ong, Yiming Pan +9
We show that by combining high-k dielectric substrate and high density of charge carriers, Coulomb impurity can be effectively screened, leading to an unprecedented room-temperatur…
High-Performance Monolayer WS2 Field-effect Transistors on High-k Dielectrics
Yang Cui, Run Xin, Zhihao Yu +13
The combination of high-quality Al2O3 dielectric and thiol chemistry passivation can effectively reduce the density of interface traps and Coulomb impurities of WS2, leading to a s…
The Electronic Properties of Phosphorene/Graphene and Phosphorene/Hexagonal Boron Nitride Heterostructures
Yongqing Cai, Gang Zhang, Yong-Wei Zhang
Vertical integration of two-dimensional materials has recently emerged as an exciting method for the design of novel electronic and optoelectronic devices. Using density functional…
Giant Phononic Anisotropy and Unusual Anharmonicity of Phosphorene: Interlayer Coupling and Strain Engineering
Yongqing Cai, Qingqing Ke, Gang Zhang +3
Phosphorene, an emerging elemental two-dimensional (2D) direct band gap semiconductor with fascinating structural and electronic properties distinctively different from other 2D ma…
Energetics, Charge Transfer and Magnetism of Small Molecules Physisorbed on Phosphorene
Yongqing Cai, Qingqing Ke, Gang Zhang +1
First-principles calculations are performed to investigate the interaction of physisorbed small molecules, including CO, H2, H2O, NH3, NO, NO2, and O2, with phosphorene, and their…
