Figure 5From: Synthesis of highly transparent ultrananocrystalline diamond films from a low-pressure, low-temperature focused microwave plasma jetOptical transmittance spectrum and AFM images. (a) Optical transmittance spectrum of the UNCD films grown by the LPLT (30 Torr/460°C) MEG process with a thickness of approximately 250 nm. (b) The corresponding AFM image of MEG UNCD films. (c) AFM image of diamond films grown at 100 Torr.Back to article page
