Topological Insulator-Superconductor Heterostructures and Devices
(University of Waterloo, 2019-09-19)A 3D topological insulator has fully gapped insulating bulk state but a conducting surface. Such conducting “surface” states are formed with helical Dirac fermions, with spin-momentum strictly locked by spin-orbital coupling. ... -
Topological Semimetals
(University of Waterloo, 2012-08-31)This thesis describes two topological phases of matter, the Weyl semimetal and the line node semimetal, that are related to but distinct from topological insulator phases. These new topological phases are semimetallic, ...
