Metal-Insulator Transition in Variably Doped (Bi1-xSbx)2Se3 Nanosheets
Chee Huei Lee, Rui He, ZhenHua Wang +8
Topological insulators are novel quantum materials with metallic surface transport, but insulating bulk behavior. Often, topological insulators are dominated by bulk contributions…

Ambipolar Surface Conduction in Ternary Topological Insulator Bi_2(Te_{1-x}Se_x)_3 Nanoribbons
ZhenHua Wang, Richard L. J. Qiu, Chee Huei Lee +2
We report the composition and gate voltage induced tuning of transport properties in chemically synthesized Bi2(Te1-xSex)3 nanoribbons. It is found that increasing Se concentration…
