Abstract
Characterization results on hydrogenated microcrystalline silicon (μc-Si:H) thin films grown in a Saddle Field (SF) PECVD system are presented. The microcrystalline content of the films is controlled by the application of a positive electrical bias to the film growth surface. The results of photoluminescence, atomic force microscopy, infrared-absorption, and electrical conductivity studies are presented. The results correlate to the changing microcrystalline content of the films in the same way as when microcrystalline content is influenced through growth parameters such as hydrogen dilution in other CVD techniques.

Notes
The crystallinity is calculated for films on either SnO2:F, f-SiO2, or CG7059 substrates, whereas the H-content is calculated for films on crystalline wafers.
