Accepted: 30 November 1995
We report on a study of transport through metal-insulator-superconductor structures where the insulator is of the Anderson type. The I -V characteristics of such samples cross over from Andreev-dominated tunnelling to single-particle tunnelling as the normal-state resistance of the device exceeds .
