Scaling of Vertical InAs–GaSb Nanowire Tunneling Field-Effect Transistors on Si
Författare
Summary, in English
We demonstrate improved performance due to enhanced electrostatic control achieved by diameter scaling and gate placement in vertical InAs-GaSb tunneling field-effect transistors integrated on Si substrates. The best subthreshold swing, 68 mV/decade at VDS=0.3 V, was achieved for a device with 20-nm InAs diamter. The on-current for the same device was 35 µA/µm at VGS=0.5 V and VDS=0.5 V. The fabrication technique used allows downscaling of the InAs diameter down to 11 nm with a flexible gate placement.
