Abstract
Using Raman spectroscopy we studied the InAs-related vibrations of a single highly strained InAs monolayer embedded in bulk-like GaAs. Experiments wer e performed in right-angle and forward-scattering configuration with the sc attered light propagating along the monolayer plane. The energies of the In As modes are strongly blue-shifted compared to the bulk values. We estimate the phonon deformation potentials of InAs and obtained the strain in the m onolayer to be -5%.
