Abstract:
We have investigated electrical transport in undoped diamond films prepared by chemical vapor deposition. Using an electrolytic decoration scheme we prove that currents flow predominantly on grain boundaries. From the temperature and the frequency dependencies we conclude that hopping transport takes place. The conductivity at different temperatures is shown to scale according to a universal curve from a random walk model.
