Engineering topological superlattices : Phase diagrams and electronic properties
ORAL
Abstract
So far, the majority of topological materials being investigated have been bulk crystals or thin films. A much less-explored area is combining diferent topological materials with trivial insulators and creating a new topological phases with distinct electronic properties, in the form of topological superlattices. We have studied a topological superlattice composed of topological insulator Bi2Se3, and normal insulator In2Se3 of different thickness. In this talk, we will discuss the low-temperature magnetotransport measurements and field theoretical calculations which show how the electronic properties of topological superlattices evolve with unit-layer thicknesses. We will further discuss if it is plausible to implement other more complex topological phases such as artificial 3D Dirac and Weyl semimetals from TI superlattices
