Abstract
We have enhanced the mobility of pentacene OTFTs using NH3 -annealed SiO2 as gate dielectric and this annealing method is often applied in the semiconductor industry for inorganic transistors. The device has field-effect mobility higher than 0.5 cm2/Vs, with on/off current ratio larger than 106, and subthreshold slope less than 2.5 V per decade. When compared with the control sample, which uses N2 -annealed SiO2 , the mobility of the proposed pentacene OTFT increases by over 50%.
