Lm. Dolginov et al., THE EFFECT OF GD DOPING ON CARRIER CONCENTRATION IN INGAASSB LAYERS GROWN BY LIQUID-PHASE EPITAXY, Thin solid films, 251(2), 1994, pp. 147-150
It is shown that addition of Gd to the melt during liquid phase epitax
y growth of InGaAsSb layers greatly reduces contamination of the sampl
es with residual donor impurities, such as sulfur and silicon. The eff
ect is related to Gd gettering of these impurities in the melt.
