Abstract A novel μc-Si:F:H film growth technique has been developed using a windowless photo-enhanced chemical vapor deposition (photo-CVD) system. The films contain of two phases with the microcrystallites embedded in amorphous materials. The films contain the crystallites with volume of fraction of 0.17-0.23 and average grain size of 32-85nm. The conductivity up to 16(Ω.cm)-1 and gauge factor (GF) of about 12 are obtained.
