Abstract
Analysis of conductivity data taken over the temperature range 4.2-0.3K for a compensated sample of InP on the insulating side of the metal-insulator transition in terms of the relation sigma = sigma 0exp(-(T0/T)s) indicates that s=1/2, in agreement with the Efros and Shklovskii (1975) Coulomb gap prediction.Keywords
