Abstract
Our interest is centred on the very thin layers consisting of only one or a few monolayers of InAs. The optical transition energies, measure d by photoluminescence spectroscopy, are compared with theoretical cal culations obtained in envelope function approximation and through an e mpirical tight-binding method. This comparison yields values for the n ot well-known valence band offset at the InAs/InP interface, and the l uminescence lines observed at different energies could be assigned to layers between one and 13 monolayers thick.
