Abstract : A study of erbium doping of molecular beam epitaxy(MBE) grown gallium arsenide layers was initiated. In the present work, the low temperature photoluminescence of Er in GaAs was confirmed and the growth conditions necessary to produce Er doped layers were established. Secondary ion mass spectrometry (SIMS) data on the MBE grown GaAs:Er doped layers confirm the presence of Er in the layers and the increase in Er doping with source temperature. Photoluminescence measurements on three samples of MBE grown GaAs: Er layers were very interesting. There is no evidence of any broad background which is observed in ion-implanted samples. The intense and sharply structured photoluminescence of MBE grown Er doped GaAs centered around 1.54 microns has been confirmed.
