WebAug 28, 2014 · 28 August 2014. Physics. Weak localization and weak anti-localization are quantum interference effects in quantum transport in a disor- dered electron system. Weak anti-localization enhances the conductivity and weak localization suppresses the conductivity with decreasing temperature at very low temperatures. WebApr 3, 2009 · Disorder plays an important role in two dimensions, and is responsible for striking phenomena such as metal-insulator transition and the integral and fractional quantum Hall effects. In this Letter, we investigate the role of disorder in the context of the recently discovered topological insulator, …
