Influence of spin state of dislocations on the conductivity of silicon crystals
Grazhulis V.A. , Kveder V.V. , Osip'yan Yu.A.
We have observed a decrease of the conductivity of silicon crystals following saturation of the dislocation EPR signal. At helium temperatures, the effect is proportional to T~ 015. The observed phenomenon is attributed to the dependence of the interaction of the free carriers with the dislocations on the spin state of the dislocation and of the carriers themselves.
