    In this paper we present a method of using blends of two silanes with different functional groups to precisely tune the turn-on-voltage to 0V. In addition, we show how the transistor behaviour of an amorphous polymer low-voltage transistor is affected by modification of the Al2O3 dielectric with self-assembled monolayers of molecules with different functional groups. Controlling the turn-on voltage is essential for any practical applications, especially for low-voltage transistors. This method opens new doors to designing stable, low-voltage organic circuitry in a reproducible manner.
