Experimental study of crystalline n-Si(¥) showed that /, the length parameter which characterizes the nonohmic nature of the hopping conductivity with variable-range hopping, is a large value, appreciably exceeding the mean range of the hop, and that with decrease of the temperature Γ, this value increases in proportion to l~ T~ n, where η ~ 1. This behavior is consistent with the predictions of the theoretical model and the numerical calculations {Ε. I. Levin and В. I. Shklovsku, Fiz. Tekh. Poluprovodn. 18, 856 (1984) [Sov. Phys. Semicond. 18, 534 (1984)].
