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…

Ultrafast carrier and phonon dynamics in Bi2Se3 crystals
J. Qi, X. Chen, W. Yu +9
Ultrafast time-resolved differential reflectivity of Bi2Se3 crystals is studied using optical pump-probe spectroscopy. Three distinct relaxation processes are found to contribute t…
