Non-Equilibrium Carriers in Type-II Quantum Dots
Abstract
The spatial distribution and recombination of nonequilibrium electrons and holes in a system of type-II quantum dots is considered theoretically. In this system contrary to the well known type-I quantum dots system one type of carrier is confined to the dot whereas the other type is localized in a Coulomb potential well outside the dot. The alters the recombination processes dramatically and results in new intensity and temperature dependencies in the photoconductivity. Possible device applications of type-II quantum dots, in particular for photovoltaic structures, are discussed.
