Recombination-Enhanced Interactions between Point Defects and Dislocation Climb in Semiconductors

Abstract
The interaction between 100 climb-induced dislocation networks and a naturally occurring deep level (the DX center) in AlxGa1xAs has been analyzed by scanning deeplevel transient spectroscopy. The concentration of DX centers was observed to decrease markedly in the vicinity of climb-induced 100 networks, but remained nearly unchanged near glide-induced 110 dislocation networks.
