ABSTRACT:
A diamond film having an intensity ratio of diamond-Raman-peak-to-photoluminescence background intensity greater than about 20, a maximum intensity of the diamond Raman peak in counts/sec divided by the intensity of photoluminescence at 1270 cm greater than about 3, a Raman sp full width half maximum less than about 6 cm and a diamond-to-graphite Raman ratio greater than about 25. The diamond film has a thermal conductivity of at least 17 Wcm K.
