2D-Dirac surface states and bulk gap probed via quantum capacitance in a 3D topological insulator

Jimin Wang, Cosimo Gorini, Klaus Richter +3

BiSbTeSe $_{2}$ is a 3D topological insulator (3D-TI) with Dirac type surface states and low bulk carrier density, as donors and acceptors compensate each other. Dominating low temper…

Capacitance-voltage measurements of (Bi $_{1 - x}$ Sb $_{x}$ ) $_{2}$ Te $_{3}$ field effect device

Jimin Wang, Markus Schitko, Gregor Mussler +2

Capacitance-voltage ( $C-V$ ) traces in n-type-(Bi $_{1 - x}$ Sb $_{x}$ ) $_{2}$ Te $_{3}$ /oxide/metal capacitor structures using an AC capacitance bridge are investigated. By tuning the t…
