The researchers report on the first experimental demonstration of p-channel GaSb homo-junction (Homj) and InAs-GaSb broken-gap hetero-junction TFETs. Broken-gap TFETs exhibit a drive current (ION) of 35 μA/um at VDS= -0.5V, 115X enhancement over the GaSb Homj and is the highest value reported till date among III-V p-channel TFETs. The effect of scaling body thickness (Tbody) and structural quantization achieving high on-current and high on-off ratio in broken-gap complementary TFETs is presented.
