EPR and optical studies on as grown polycrystalline diamond and diamond films annealed between 1100 and 1900 K

Abstract:

We report a systematic study by electron paramagnetic resonance (EPR), and infrared absorption of as grown and annealed free standing polycrystalline diamond films. In all CVD diamond films studied an EPR resonance is observed at g=2.0028(2). Comparison of the local and bulk concentrations indicated that these centres are inhomogeneously distributed in the films, where as the single substitutional nitrogen centres appear homogeneously distributed throughout the CVD diamond. The strength of th...
