Abstract
In recent years tunnel FETs (TFETs) have attracted a great deal of attention [1–9]. The reason for this is that TFETs potentially allow beating the 60mV/dec limit and thus eventually enable lowering the power consumption of ICs. However, TFETs usually exhibit an onstate performance inferior to a conventional MOSFET. Moreover, in order to obtain a superior off-state TFETs must exhibit subthreshold swings substantially smaller than 60mV/dec over several orders of magnitude in current. In the present paper the impact of device structure, dimensions and the choice of material on the performance of TFETs will be discussed. In particular, the use of heterostructures and one-dimensional nanowires will be analyzed in detail.
