Scholarcy highlights

  • We present a tight-binding calculation of the interband optical transitions in semiconductor quantum dots
  • The calculated optical-absorption spectra are in good agreement with the existing experimental spectra of CdS and CdSe QD’s
  • The comparatively stringent selection rules of the latter are applicable to a large extent
  • See Off-Campus Access to Physical Review for further instructions
