Query: Lateral optical anisotropy of type-II interfaces in the tight-binding
  approach   We have developed the tight-binding theory to study electronic and optical
properties of type-II heterostructures CA/C'A' grown from the zinc-blende
semiconductors CA and C'A' along the crystallographic direction [001]. The
sp^3s* nearest-neighbor tight-binding model with allowance for the spin-orbit
interaction is used to calculate the energy states and the in-plane linear
polarization of the spatially-indirect band-edge photoluminescence of InAs/AlSb
and ZnSe/BeTe multi-layered structures. The interface parameters for a pair of
the nonstandard planes C-A' or C'-A are considered as fitting variables. A wide
range of these parameters are shown to allow Tamm-like hole states localized at
the interfaces. The theory leads to giant values of the light polarization in
the both type-II heterosystems in agreement with existing experimental
findings.
