Band structure engineering in (Bi(1-x)Sb(x))(2)Te(3) ternary topological insulators.
Topological insulators (TIs) are quantum materials with insulating bulk and topologically protected metallic surfaces with Dirac-like band structure. The most challenging problem faced by current investigations of these materials is to establish the existence of significant bulk conduction. Here we show how the band structure of topological insulators can be engineered by molecular beam epitaxy...
متن کاملFew-layer nanoplates of Bi 2 Se 3 and Bi 2 Te 3 with highly tunable chemical potential.
A topological insulator (TI) represents an unconventional quantum phase of matter with insulating bulk band gap and metallic surface states. Recent theoretical calculations and photoemission spectroscopy measurements show that group V-VI materials Bi(2)Se(3), Bi(2)Te(3), and Sb(2)Te(3) are TIs with a single Dirac cone on the surface. These materials have anisotropic, layered structures, in whic...

متن کاملStructural Characterization of the Cu2(Se,Te)3-(Ga,In)2(Se,Te)3 Semiconducting Systems
Many contributions have been reported in the literature about the synthesis and characterization of chalcopyrite-related Inand Ga-rich ordered defect compounds of the ternary systems: Cu-In-Se, Cu-In-Te, Cu-Ga-Se and Cu-GaTe. Particular interest has been paid to the compounds that can be derived from the formula CuN-3InN+1Se2N, where N=4, 5, 6, 7, 8 and 9, because some of these materials have a...
