Abstract:
1. A semiconductor structure comprising: a semiconductor portion including at least one dopant atom and abutting, and encapsulated by a dielectric material layer and a top surface of an insulator layer, wherein said dielectric material layer is continuously present on sidewall surfaces of said semiconductor portion and on an uppermost surface of said semiconductor portion, and said dielectric material layer on the sidewall surfaces of said semiconductor portion and on the uppermost surface of the said semiconductor portion has a same thickness; a gate conductor vertically abutting a first portion of said dielectric material layer present on said uppermost surface of said semiconductor portion; a source-side conductive material portion laterally abutting a second portion of said dielectric material layer present on one of the sidewall surfaces of the semiconductor portion; and a drain-side conductive material portion laterally abutting a third portion of said dielectric material layer present on another of the sidewall surfaces of the semiconductor portion, wherein said thickness of said dielectric material layer is less than 2 nm to enable quantum tunneling of electrical current.
