Abstract :
The influence of substrate bias voltage on p-type carbon nanotube MOSFET (CN-MOSFET) performance is investigated in this paper. Tradeoffs between subthreshold leakage current and device speed are evaluated with two different substrate bias voltages. P-channel CN-MOSFETs are optimized for achieving the maximum on-state to off-state current ratio (Ion/Ioff) with a higher substrate bias voltage. Connecting the substrate to the power supply is recommended for enhanced overall switch quality in p-channel carbon nanotube transistors.
