Structural and electronic properties of highly doped topological insulator Bi2Se3 crystals
Helin Cao, Suyang Xu, Ireneusz Miotkowski +4
We present a study of the structural and electronic properties of highly doped topological insulator Bi2Se3 single crystals synthesized by the Bridgman method. Lattice structural c…
AFM and Raman studies of topological insulator materials subject to argon plasma etching
Isaac Childres, Jifa Tian, Ireneusz Miotkowski +1
Plasma etching is an important tool in nano-device fabrication. We report a study on argon plasma etching of topological insulator materials Bi2Se3, Bi2Te3, Sb2Te3 and Bi2Te2Se usi…
Ultrafast surface carrier dynamics in the topological insulator Bi2Te3
M. Hajlaoui, E. Papalazarou, J. Mauchain +9
We discuss the ultrafast evolution of the surface electronic structure of the topological insulator BiTe following a femtosecond laser excitation. Using time and angle reso…
