Plastic homology of tetrabonded crystals

摘要

The temperature dependence of the critical resolved shear stress of tetrabonded crystals Si, Ge, SiC, diamond, GaP, GaAs, GaSb, CdTe, HgSe, CuCl and CuBr follows a universal re- Lationship: all τ_c(T) data lie on one and the same master curve τ_c/G vs kT/Gb~3, where G is the shear mod- Ulus and b the length of the total Burgersvector.
