Impurity scattering in the bulk of topological insulators
Cheung Chan, Tai-Kai Ng
We study in this paper time-reversal -impurity scattering effects in the bulk of topological insulators (TI) in two and three dimensions. Specifically we consider how impurity s…

Out of plane screening and dipolar interactions in heterostructures
Cheung Chan, T. K. Ng
Out-of-plane screening (OPS) is expected to occur generally in metal-semiconductor interfaces but this aspect has been overlooked in previous studies. In this paper we study the ef…
