Variation of the prefactor as a function of for all the studied films deposited at different rf powers as indicated, assuming a band-tail hopping transport mechanism, compared to the results for other amorphous carbon-based materials: a-C (Ref. 16), a-C:H (Ref. 12), (Ref. 17). The dotted line is the simulation from the bandtail hopping model.
