Valley Gapless Semiconductor: Models and Applications
Kok Wai Lee, Pei-Hao Fu, Jun-Feng Liu +2
The emerging field of valleytronics harnesses the valley degree of freedom of electrons, akin to how electronic and spintronic devices utilize the charge and spin degrees of freedo…
Floquet engineering of topological phase transitions in quantum spin Hall - system
Kok Wai Lee, Mateo Jalen Andrew Calderon, Xiang-Long Yu +3
Floquet engineering of topological phase transitions driven by a high-frequency time-periodic field is a promising approach to realizing new topological phases of matter distinct f…
Interplay between Haldane and modified Haldane models in - lattice: Band structures, phase diagrams and edge states
Kok Wai Lee, Pei-Hao Fu, Yee Sin Ang
We study the topological properties of the Haldane and modified Haldane models in - lattice. The band structures and phase diagrams of the system are investigated. Indivi…
Injection-Limited and Space-Charge-Limited Conduction in Wide Bandgap Semiconductors with Velocity Saturation Effect
Kok Wai Lee, Yee Sin Ang
Carrier conduction in wide bandgap semiconductors (WBS) often exhibits velocity saturation at the high-electric field regime. How such effect influences the transition between cont…
