Pseudopotential study of electron-hole excitations in colloidal free-standing InAs quantum dots
Pseudopotential study of electron-hole excitations in colloidal free-standing InAs quantum dots
Excitonic spectra are calculated for free-standing, surface passivated, InAs quantum dots using atomic pseudopotentials for the single-particle states and screened Coulomb interactions for the two-body terms. We present an analysis of the single particle states involved in each excitation in terms of their angular momenta and Bloch-wave parentage. We find …
