Hopping conduction in partially compensated doped silicon

Abstract
We have measured the dc electrical resistance of partially compensated (5–50 %) ion-implanted Si:P,B (both n and p type), over the temperature range 0.05–30 K. The temperature behavior is consistent with the prediction of the model for variable-range hopping (VRH) with a Coulomb gap ρ(T)=ρ0exp(T0/T)1/2 over a temperature range 6.5T0/T
