Infrared probe of the insulator-to-metal transition in Ga1−xMnxAs and Ga1−xBexAs
We report infrared studies of the insulator-to-metal transition (IMT) in GaAs doped with either magnetic (Mn) or nonmagnetic acceptors (Be).

Fabrication and characterization of topological insulator Bi2Se3 nanocrystals
In the recently discovered class of materials known as topological insulators, the presence of strong spin-orbit coupling causes certain topological
