Electrical property dependence on thickness and morphology of nanocrystalline diamond thin films
In this study, we investigate the influence of nanocrystalline diamond (NCD) thin film morphology and thickness on their electrical properties. NCD films are grown on p-type Si substrates with varied thicknesses from 250 to 788nm. Electrical contacts are formed from combination of Ti/Au metal layers (100nm thick each). The IV and breakdown field measurements are used to analyze the electrical properties of metal/NCD/Si sandwich structure. In addition, NCD films are analyzed by scanning electron microscopy and Raman spectroscopy for better interpretation of the IV measurements.
