Abstract
A series of compressively strained G(0.44)In(0.56)P/(Al0.7Ga0.3)(0.52) In-0.48 P multiple quantum well structures have been studied in magnet ic fields up to 45 T. Laudau levels from several excitomic transitions have been observed in reflectivity spectra, allowing an accurate dete rmination of the carrier masses and excitonic binding energies. It is shown that while the observed masses are lower than those seen in unst ained GaInP/AlGaInP for wide wells, as the width decreases the mass in the strained samples increases sharply.
