US Patent 11121243 2D-3D heterojunction tunnel field-effect transistor

Disclosed is a 2D-3D HJ-TFET made of a material, the band gap of which changes according to the thickness, such as black phosphorous or TMDC, in order to extend Moore's law. More particularly, disclosed are the structure of a 2D-3D HJ-TFET and a method for manufacturing the same, wherein the 2D-3D HJ-TFET is made of a material such as black phosphorous or TMDC such that the same consumes less power, has a high switching speed, can operate in a complementary manner so as to replace a conventional CMOS transistor, and can extend Moore's law.
