Abstract
We demonstrate a vertical InAs nanowire MOSFET integrated on Si substrate with an extrinsic peak cut-off frequency of 103 GHz and a maximum oscillation frequency of 155 GHz. The transistor has a transconductance of 730 mS/mm and is based on arrays of nanowires with gate-all-around and high-κ gate dielectric. Furthermore, small-signal modeling shows a ~80% reduction of the total parasitic gate capacitance when the metal pad overlap in the transistors is reduced through additional patterning.
