El. Ivchenko, FINE-STRUCTURE OF EXCITONIC LEVELS IN SEMICONDUCTOR NANOSTRUCTURES, Physica status solidi. a, Applied research, 164(1), 1997, pp. 487-492
A brief survey is given on recent work on the fine structure of zero-d
imensional excitons in semiconductors. The paper focuses on microscopi
c mechanisms of anisotropic exchange splitting of the localized-excito
n radiative doublet in type-I and type-II heterostructures and on pola
rized photoluminescence of excitons confined in self-assembled quantum
dots.
