Two respective top - gate NW FETs with Au and indium - tin - oxide ( ITO ) were connected to form an inverter , the basic NOT gate component , since the former gate leads to an enhanced mode FET while the latter to depletion mode due to their work function difference .
 Chemical: Au; Chemical: indium - tin - oxide; Chemical: ITO
