MINIBAND STRUCTURES AND DENSITIES OF IMPURITY STATES IN LATERAL-SURFACE-SUPERLATTICE QUANTUM-WELL WIRES

We calculate energy miniband structures and densities of impurity stat es in quasi-one-dimensional GaAs/AlAs quantum well wires with periodic lateral surface structures. By a coordinate transformation, the struc tured interfaces of the wires are transformed into planar interfaces s o that the boundary conditions of the electronic wavefunctions can be satisfied exactly on the interfaces. The new optical transition spectr al structures associated with minibands and impurities are discussed.
