ABSTRACT
Photoreflectance experiments with magnetic fields up to 14.5 T are performed on epitaxial GaAs and GaAs/Ga1-xAlxAs quantum well samples at room temperature and 2 K. Our experiments show unique and direct evidence that photoreflectance structures are excitonic transitions in all of the above cases.

    We report the remarkable observation of strong room-temperature excitonic features in the absorption spectra of GaAs-AlxGa1-xAs quantum wells (QWs) for values of x as low as 0.02.

    We resonantly excite excitons associated with the second electron and heavy hole subbands (n=2 excitons) in 13 and 17.5 nm GaAs quantum wells (QWs) at 8 K to perform femtosecond degenerate four wave mixing measurements. We deduce the lifetime T[sub 1] of the n=2 excitons to be approx. 890 fs and...
