Semiconductor device and method of manufacturing the same

Abstract

A semiconductor device includes a two-dimensional semiconductor layer formed by a two-dimensional semiconductor material having a first formation energy, a two-dimensional metal conductor layer formed by a two-dimensional metal material and covering a surface of the two-dimensional semiconductor layer, and a metal layer covering a surface of the two-dimensional metal conductor layer. The two-dimensional metal material has a second formation energy smaller than the first formation energy. The two-dimensional metal conductor layer is formed by bonding of cations from the metal layer and anions from the two-dimensional semiconductor layer. As such, the contact resistances between the two-dimensional materials and the metals can be effectively reduced, enabling the application of the two-dimensional materials in semiconductor devices such as field-effect transistors.
