摘要：

An organic field-effect transistor able to switch from depletion (normally on) to enhancement (normally off) mode was obtained thanks to the composition of the mixed semiconductor that forms the device channel. The threshold voltage of the device can be predictably tuned from positive to negative values by adjusting the composition of a mixture of sexithiophene derivatives that are able to achieve a perfect intercalation inside the thin film.
