Abstract:
1. A thin film transistor, comprising: a substrate; a plurality of 2D atomic crystal layers formed atop the substrate, wherein the plurality of 2D atomic crystal layers comprise a 2D atomic crystal high-k insulator layer formed atop a 2D atomic crystal semiconductor layer; an interface between the 2D atomic crystal semiconductor layer and the 2D atomic crystal high-k insulator layer, wherein the interface comprises van-der-Waals bonds; a source electrode and a drain electrode disposed atop the 2D atomic crystal semiconductor layer in respective source and drain regions of the thin film transistor, wherein the source electrode and drain electrode define a channel region disposed between the source and drain regions; and a gate electrode disposed atop 2D atomic crystal high-k insulator layer, wherein the 2D atomic crystal high-k insulator layer comprises an electrically insulating transition metal dichalcogenide and the 2D atomic crystal semiconductor layer comprises a semiconducting transition metal dichalcogenide.
