Popis: |
The laser express technique has been applied to high temperature measurements of CVD diamond reflectivity R and absorption coefficient (alpha) for radiation with 1.06 mm wavelength as well as heat capacity. It was found that at T > 1000 degrees C and heating cycles of a few seconds the sample surface layer with thickness of 100 nm becomes graphitized that leads to dramatic growth of (alpha) from initial value of about 10 cm-1. The obtained results on heat capacity at T >= 800 degrees C are well matched with the known data at lower temperatures.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
