Traditional transistors, the building blocks of modern electronics, are primarily made from silicon. However, as we strive to make these transistors smaller and more powerful, silicon faces inherent limitations. These limitations include:

These challenges can lead to slower performance, increased power consumption, and ultimately, limit the capabilities of our electronic devices.

Leakage Current: Silicon transistors can experience unwanted current leakage, leading to wasted energy and reduced efficiency.
Short Channel Effects: As transistors shrink, controlling the flow of current becomes more difficult, impacting performance.
Mobility Issues: The speed at which electrons can move through silicon is limited, restricting the overall speed of the transistor.

CNTFETs, on the other hand, offer a compelling solution to these problems. By utilizing carbon nanotubes—tiny cylinders of carbon atoms with exceptional electrical properties—CNTFETs can achieve:
