Abstract

Significant progress has been made in the area of p-type organic field-effect transistors while progress in developing n-type materials and devices has been comparatively lacking, a limiting factor in the pursuit to develop complementary organic electronic circuits. Given the need for n-type organic semiconductors we have carried out studies using two different fullerene molecules, C₆₀ and C₇₀. Here, we report mobilities for C₆₀ ranging from 0.02 cm²/Vs up to 0.65 cm²/Vs (depending on channel length), and mobilities from 0.003 cm²/Vs up to 0.066 cm²/Vs for C₇₀. All devices were fabricated with organic films deposited under high vacuum but tested at ambient pressures under nitrogen.
