NANOWIRE TUNNEL DIODE AND METHOD FOR MAKING THE SAME

摘要

The present invention provides a tunnel diode and a method for manufacturing thereof. The tunnel diode comprises a p-doped semiconductor region and an n-doped semiconductor region forming a pn-junction at least partly within a nanowire where semiconductor materials on different sides of the pn-junction are different such that a heterojuction is formed. The materials of the nanowire may be compound semiconductor materials. The heterojunction tunnel diode can be of type-I (Straddling gap), type-II (Staggered gap) or type-III (Broken gap).
