Why are nanowires proposed to be used in MOSFETs? Correct Answer High aspect ratio

The high aspect ratio of nanowires controls the channel electrostatic potential when the gate dielectric remains wrapped around the nanowire channel. This would turn the transistor on and off effectively. Therefore, metal-oxide semiconductor field effect transistors make use of nanowires.
