Abstract

The transport properties of two device-related semiconductor microstructure quantum-well systems are addressed here. The first involves the theory of negative differential mini-band conductance (NDC) in a lateral semiconductor superlattice of very thin quantum dots laid out in a square array on a plane, both with and without a normal magnetic field. NDC of the total current is made steeper by the magnetic field, and the Hall coefficient is shown to exhibit hole features near the electron energy band top. The second system discussed here is composed of two parallel planar quantum wells separated by a potential barrier, which exhibits electron-hole Coulomb drag effects shown to involve nonlinearity.
