In this work we investigate by numerical simulation the achievable performance of a steep-slope nanowire FET based on the filtering of the high-energy electrons by a superlattice heterostructure in the source extension. After a preliminary study aimed to identify the most promising material pairs for the superlattice with respect to the typical FET evaluation metrics, we concentrate on a superlattice-based FET employing the InGaAs-InAlAs pair, which provides a good switching slope and an excellent on-current. The device optimization leads to a prediction of an inverse SS = 35 mV/dec and an on-current exceeding 2.3 mA/μm at a supply voltage of 400 mV.

Abstract

In this work we investigate by numerical simulation the achievable performance of a steep-slope nanowire FET based on the filtering of the high-energy electrons by a superlattice heterostructure in the source extension. After a preliminary study aimed to identify the most promising material pairs for the superlattice with respect to the typical FET evaluation metrics, we concentrate on a superlattice-based FET employing the InGaAs-InAlAs pair, which provides a good switching slope and an excellent on-current. The device optimization leads to a prediction of an inverse SS = 35 mV/dec and an on-current exceeding 2.3 mA/μm at a supply voltage of 400 mV.
