Abstract: | An inductively coupled, intense, pulsed RF plasma source deposited plasma-polymerized acetylene at a rate of 127 Å per discharge. The potassium bromide substrate was located 18-cm downstream from the RF coil. A puff valve admitted parent acetylene gas just before the transient RF current was applied. Fourier transform infrared (FTIR) spectra showed that carbon-to-carbon double bonds were formed. Scanning-electron-microscope images showed that the film thickness after 79 discharges was 1 μm. A photodiode showed substantial light emission for about 30 μs during each discharge |
