REFLECTANCE DIFFERENCE SPECTROSCOPY OF GAAS ASYMMETRIC SURFACE QUANTUM WELLS ABOVE THE FUNDAMENTAL GAP

We report Reflectance Difference (RD) measurement on (001) GaAs surface quantum wells (QW) under Ultra High Vacuum (UHV) conditions from 1.7 to 5.0eV. The QW is embedded between an arsenic-rich rec ...
