A new design for a field effect transistor able to push back the physical limits of Moorešs Law is described. The ON state of the device is characterized using ab initio computer simulation. An electron introduced on one side of the conjugated molecular switching element can move across to the other side of the molecule in an electric field in the absence of a gate voltage, a process analogous to conduction. The presence of a gate voltage effectively interrupts conjugation and suppresses conduction. A molecular-based processor of this type could demonstrate transistor density of up to 2 x 1012 transistors per cm2 and run at up to 12 THz.
