3.4: Dislocation nucleation and multiplication

[@namigalasgarzade7727]

Dear Kelvin, thank you for the nice explanation. I have a question about dislocation multiplication. As far as I understood, there is a critical stress for dislocation multiplication,but how about temperature? Is it possible to achieve dislocation multiplication in silicon at room temperature?

Hi Namig, the lattice resistance is too high for Si. Moreover, Si can undergo phase transformation, which competes with dislocation-mediated plasticity. Thus it is difficult to have dislocation multiplication in Si at RT.
