Abstract

We report experimental demonstration of a right-angle black phosphorus (BP) tunneling field effect transistor (TFET). This device utilizes the effective mass anisotropy between the armchair (AC) and zigzag (ZZ) crystal orientations in BP as a means of inducing asymmetry between source and drain tunneling. As a result of this asymmetry, the BP TFET displays a higher {I} {\mathrm{\scriptscriptstyle ON}} / {I} { \mathrm{\scriptscriptstyle OFF}} ratio by 2 orders of magnitude and steeper SS than BP TFETs oriented along either the AC or ZZ direction only.
