Abstract

We propose a theory of interference contributions to the two-dimensional exciton diffusion coefficient. The theory takes into account four spin states of the heavy-hole exciton. The interplay of the single-particle (electron and hole) spin splittings with the electron-hole exchange interaction gives rise to either localization or antilocalization behavior of excitons, depending on the system parameters. Possible experimental manifestations of exciton interference are discussed.
