Deep level transient spectroscopy of CVD diamond: the observation of defect states in hydrogenated films

Abstract:

Hydrogenated polycrystalline CVD diamond films support a number of defect states within the range 0.03-1.0 eV, as determined by charge-based deep level transient spectroscopy (Q-DLTS). The observation of a 30-meV state is direct evidence for such a shallow level in this material, and is most likely to be the acceptor state that gives rise to the p-type character of these films. Deeper levels, at 0.11 eV, 0.39 eV, 0.65 eV and 0.70 eV-1.0 eV can also be observed and again appear to be associate...
