Logic circuit function realization by one transistor.

Bottom-up nanowires are very attractive building blocks for functional devices due to their controllable properties. Meanwhile, assembling nanowires into large-scale integrated circuits is a daunting challenge because for the present circuits diverse nanowires are needed to grow simultaneously together closely. Here, a nanowire trigate transistor structure is proposed which can accomplish the functions of the logic gate circuits. By adding one channel-electrode junction as the output, this interesting one-channel structure is used to realize inverter and OR logic gates. In this way, logic circuits could shrink into a single transistor.
