Magnetotransport of coupled electron-holes
arXiv:cond-mat/0008004 · doi:10.1209/epl/i2001-00450-8
Abstract
The carriers in InAs-GaSb double quantum wells are hybrid ``electron-holes''. We study the magnetotransport properties of such particles using a two-component Keldysh technique, which results in a semi-analytic expression for the small-field current. We show that zero temperature current can be large even when the Fermi energy lies within the hybridization gap, a result which cannot be understood within a semiclassical (Boltzmann) approach. Magnetic field dependence of the conductance is also affected significantly by the hybridization of electrons and holes.
