Notes:
We describe new results observed during resonant excitation in the excitonic region of GaAs grown directly on Si by organometallic vapor phase epitaxy. Two resolved features were found in the light-hole photoluminescence (PL) region, one identified with a free-exciton process and the other with donor-related transitions. Inhomogeneous line broadening was observed for the excitonic PL lines and related to stress fluctuations. Features which track the laser excitation line were observed and identified with a process in which a donor is excited from the n=1 ground state to an n=2 state.
