Abstract
A photoluminescence study of emission from a periodically perforated quantum well at 77 K is presented. Good agreement is observed between numerical predictions and experimental results. The effects of pore diameter on peak emission wavelength and relative emission from second excited subbands are analyzed. The results are found to be consistent with predictions of reduced intersubband scattering rate in nanopore lattices due to the reduced wave function overlap between the initial and final states arising from the in-plane periodicity.
