Scanning tunneling microscopy of defect states in the semiconductor (formula presented)
Urazhdin, S.; Bilc, D. I.; Tessmer, S. H.; Mahanti, S. D.; Kyratsi, Theodora; Kanatzidis, M. G. (2002)Scanning tunneling spectroscopy images of (formula presented) doped with excess Bi reveal electronic defect states with a striking shape resembling clover leaves. With a simple tight-binding model, we show that the geometry ...

Surface effects in layered semiconductors Bi2Se3 and Bi2Te3
Urazhdin, S.; Bilc, D. I.; Mahanti, S. D.; Tessmer, S. H.; Kyratsi, Theodora; Kanatzidis, M. G. (2004)Scanning tunneling spectroscopy of Bi2Se3 and Bi2Te3 layered narrow gap semiconductors reveals finite in-gap density of states and suppressed conduction in the energy range of high valence-band states. Electronic structure ...
