Light-hole quantization in the optical response of ultrawide GaAs/Al${}_x$Ga${}_{1-x}$As quantum wells

V. V. Solovyev, V. A. Bunakov, S. Schmult +1

Temperature-dependent reflectivity and photoluminescence spectra are studied for undoped ultra-wide 150 nm and 250 nm GaAs quantum wells. It is shown that spectral features previou…
