Abstract

High quality In0.53Ga0.47As is grown on semi-insulating (100) InP:Fe substrates. The growths are performed with rare-earth dope liquid phase epitaxial (LPE) growth melts in a graphite boat. Hall measurements show improved electron mobility and reduced (n-type) carrier concentration. Photoluminescence (PL) shows rare-earth doped layer have a higher PL efficiency with narrower linewidths that undoped layers. However, two deep levels are created by the rare earth elements. These results confirm previous reports that rare-earth elements added to the LPE growth melt can actually lower the level of impurities within the epitaxial layer.
