Abstract In order to investigate the importance of the dislocation velocity for the brittle-to-ductile transition temperature, fracture experiments were performed on precleaved, dislocation-free silicon single crystals at elevated temperatures. The well known doping dependence of the dislocation velocity in silicon is used to obtain detailed information about the conditions in the plastic zone. At high temperatures, dislocations are generated at an applied stress intensity distinctly lower than… CONTINUE READING
