Intrinsic Performance of InAs Nanowire Capacitors

Jansson, Kristofer LU ; Lind, Erik LU and Wernersson, Lars-Erik LU (2014) In IEEE Transactions on Electron Devices 61(2). p.452-459
Abstract
The intrinsic properties of vertical InAs nanowire (NW) capacitors are investigated. The band structure is simulated using a Schrödinger-Poisson solver, taking the conduction band nonparabolicity into account. This is combined with a distributed RC model to simulate the current-voltage characteristics. It is found that the influence from the nonparabolicity is substantial for devices with a small nanowire diameter, resulting in an increased carrier concentration, a shift in the threshold voltage, and a higher intrinsic capacitance. These NW capacitors may be a suitable alternative in high frequency applications approaching 100 GHz, while maintaining a quality factor above 100.
