This paper describes the fabrication and characterization of a carbon based, bottom gate, thin film transistor (TFT). The active layer is formed from highly sp2 bonded nitrogenated amorphous carbon (a-C:N) which is deposited at room temperature using a filtered cathodic vacuum arc technique. The TFT shows p-channel operation. The device exhibits a threshold voltage of 15 V and a field effect mobility of 10-4 cm2 V-1 s-1 . The valence band tail of a-C:N is observed to be much shallower than that of a-Si:H, but does not appear to severely impede the shift of the Fermi level. This may indicate that a significant proportion of the a-C tail states can still contribute to conduction.
