In the present work, several series with variation of deposition parameters such as hydrogen dilution ratio, VHF-power and plasma excitation frequency fexc have been extensively analyzed. Compared with “conventional” more-stable layers obtained at 200–250°C and high H2 dilution ratios of about 10, it was observed that electrical transport properties after...
