Abstract
Current-voltage characteristics are reported for ion-implanted Si:As, with As concentrations about 10% below the concentration of the metal-insulator transition, in the temperature range 0-07-1K. The data are analysed with both an electric-field-assisted hopping model and a heating model. It follows that, at least at the lowest temperatures (non-equilibrium), heating is the dominant effect.
