Abstract

We evaluate the impact of tunnel junction quality on the performance of tunnel field-effect transistors (TFETs). Performing a sequential surface cleaning procedure prior to epitaxial channel growth for heavily arsenic- and boron-doped Si surfaces improves the interface quality both for p- and n-TFETs. Simultaneously, the subthreshold swing (SS) values of the TFETs improve step-by-step with interface quality.
