Abstract
The magnitude and Impact of the parasitic capacitances in a vertical InAs nanowire transistor consisting of a matrix of nanowires is evaluated A simple transistor model is fitted to experimental I-V characteristics and the influence of the parasitic components on the transistor performance for different structures is investigated Simulations of the S parameters indicate an intrinsic f(T) of about 690 GHz for 50 nm L-G We show that f(T) reaches 56% of the intrinsic value in an optimized transistor structure with closely spaced nanowires and that a high wire density is more efficient to reduce the parasitics than to pattern the electrodes Finally the analytical model is used to demonstrate the operation and to simulate the performance of...
