Electrostatic Coupling between Two Surfaces of a Topological Insulator Nanodevice
We report on electronic transport measurements of dual-gated nanodevices of the low-carrier density topological insulator (TI) Bi[subscript 1.5]Sb[subscript 0.5]Te[subscript 1.7]Se[subscript 1.3]. In all devices, the upper and lower surface states are independently tunable to the Dirac point by the...
