Over-Barrier Photoelectron Emission with Rashba Spin-Orbit Coupling
Bi Hong Tiang, Yee Sin Ang, L. K. Ang
We develop a theoretical model to calculate the quantum efficiency (QE) of photoelectron emission from materials with Rashba spin-orbit coupling (RSOC) effect. In the low temperatu…
Designer Edge States in Fractional Polarization Insulators
Wei Jie Chan, Peihao Fu, L. K. Ang +1
We theoretically investigated the topological-protected edge states (TESs) in an anisotropic honeycomb lattice with mirror and chiral symmetries, characterized by an alternative to…
Universal Model of Optical-Field Electron Tunneling from Two-Dimensional Materials
Yi Luo, Yee Sin Ang, L. K. Ang
We develop analytical models of optical-field electron tunneling from the edge and surface of two-dimensional (2D) materials, including the effects of reduced dimensionality, non-p…
Quantum Shot Noise Signatures of Two-Dimensional Semi-Dirac System
Wei Jie Chan, L. K. Ang, Yee Sin Ang
Two-dimensional (D) semi-Dirac systems, such as D black phosphorus and arsenene, can exhibit a rich topological phase transition between insulating, semi-Dirac, and band inve…
Modeling of electric double layer at solid-liquid interface with spatial complexity
Cherq Chua, Chun Yun Kee, L. K. Ang +1
Electrical double layer (EDL) is formed when an electrode is in contact with an electrolyte solution, and is widely used in biophysics, electrochemistry, polymer solution and energ…
Thermal-Field Electron Emission from Three-Dimensional Topological Semimetals
Wei Jie Chan, Yee Sin Ang, L. K. Ang
A model is constructed to describe the thermal-field emission of electrons from a three-dimensional (D) topological semimetal hosting Dirac/Weyl node(s). The traditional thermal…
