Precipitation on a Dislocation

Abstract

WE have recently made a study of the effect of heat treatment on silicon crystals containing up to 1017 aluminium atoms/c.c. After heating for several hours at a temperature of 1,250° C., transmission infra-red microscopy reveals the presence of a precipitated second phase within the crystals. In samples free of dislocations, these precipitates are needle… (More)
