Electronic transport properties of heavily doped arsenic implanted silicon are reported. Hall mobility and sheet resistance as functions of temperature and frequency have been carried out both on annealed and as‐implanted silicon films. The small values of the observed Hall mobility and strong frequency dependence of the transport coefficients emphasize the drastic alteration of nonannealed material. A semiquantitative analysis of the results is conducted using both short‐range and long‐range disorder considerations (hopping and percolation).
