Mechanical data have been obtained on silicon single crystal under hydrostatic pressure between room temperature and 450°C. This temperature domain corresponds to the regime where perfect dislocations control plastic deformation. This was achieved using a D-DIA apparatus in the synchrotron beam of NSLS. Stress strain curves were deduced from X Ray diffraction and sample imaging under 5 GPa and a strain rate of 2.5 10-5 s-1. Yield stresses as a function of temperature exhibit different temperature dependence when deformation is controlled by perfect dislocations. © 2007 WILEY-VCH Verlag GmbH & Co. KGaA.
