摘要
Abstract
The mechanical strength of the nitrogen-doped Czochralski(CZ) silicon and conventional CZ silicon at room temperature and their flexure strength at high temperature have been studied by three-point bending method.It is found for the first time that due to the doping of nitrogen,the mechanical strength of silicon increased markedly at room temperature.Pinning effect of nitrogen atoms on dislocations in silicon at high temperature was also confirmed.The effects of the surface condition and the orientation of crystal on the mechanical strength at room temperature were substantiated.The mechanism of nitrogen in silicon increasing the mechanical strength at room temperature has been discussed.关键词
