Abstract

We present a detailed study on the operation of a tunneling field-effect transistor (TFET) based on onedimensional broken-gap heterostructure geometry. Using numerical simulations we show that less than 60mV/dec subthreshold swing can be obtained in this device along with MOSFET-like drive-currents. We further demonstrate that the 1D geometry is uniquely suited for this device concept. Our model broken-gap TFET has a minimum swing of ∼20mV/dec along with ∼100x increase in above-threshold current compared to the homojunction geometry. © 2009 IEEE.
