Applications for

MBE growth of Topological Insulators

Topological insulators are materials whose bulk is electrically insulating, whereas their surfaces exhibit conducting states. There are  two main classes: three-dimensional (3D) and two-dimensional (2D) material systems. The 2D topological insulators are expected to exhibit one dimensional dissipationless edge channels, while the 2D plane inside is insulating.

Materials of special interest are: HgTe, Bi2Se3  Bi2Te3, Sb2Te3, Stanene, Heusler compounds, special oxides, and many others.
