Effect of exciton localization and delocalization on magnetic-field-dependent photoluminescence linewidths in semiconductors

Conference ·
OSTI ID:10181570

Theory and data are presented for the photoluminescence linewidth in ordered and disordered semiconductor alloys (In{sub 0.48}Ga{sub 0.52}P) at low temperatures. In disordered (ordered) systems, the linewidth is due to exciton localization (exciton-impurity scattering) and increases (decreases) as a function of the field in agreement with the data.
