We investigated the substarte (Si O2 and quartz) effects on the photoresponsitivity of photosensitive polymer coated single-walled carbon nanotube (SWNT) networks. As charge trapping on quartz surface is believed to be much less significant than that observed on conventional Si O2 dielectrics, using quartz as the supporting substrate allows us to probe the nave photointeraction between the photosensitive polymers and SWNTs. The two-terminal SWNT resistor devices on quartz provide an effective yet simple methodology to discriminate electron- or hole-donating photosensitive polymers.
