Nonstoichiometric doping and Bi antisite defect in single crystal Bi2Se3

, 2012
We studied the defects of Bi2Se3 generated from Bridgman growth of stoichiometric and nonstoichiometric self-fluxes. Growth habit, lattice size, and transport properties are strongly affected by the types of defect generated.

Spin-dependent properties of a two-dimensional electron gas with ferromagnetic gates

, 2002
A theoretical prediction of the spin-dependent electron self-energy and in-plane transport of a two-dimensional electron gas in proximity with a ferromagnetic gate is presented. The application of the predicted spin-dependent properties is illustrated by

Inverted device architecture for high efficiency single-layer organic light-emitting diodes with imbalanced charge transport

Nature Communications
Many wide-gap organic semiconductors exhibit imbalanced electron and hole transport, therefore efficient organic light-emitting diodes require a multilayer architecture of electron- and hole-transport materials to confine charge recombination to the ...

Electron transport in disordered graphene

, 2006
We study electron transport properties of a monoatomic graphite layer (graphene) with different types of disorder. We show that the transport properties of the system depend strongly on the character of disorder. Away from half filling, the concentration
