Abstract
A semiconductor device includes a continuous doped substrate with a surface, a sulfur-based dielectric material layer positioned on the surface of the continuous doped substrate, a dielectric material layer positioned on the sulfur-based dielectric material layer, and a gate contact region positioned on the sulfur-based dielectric material layer. The continuous doped substrate includes silicon (Si) and the sulfur-based dielectric material includes a transition metal sulfide such as strontium zirconium sulfur (SrZrS), barium zirconium sulfur (BaZrS), strontium hafnium sulfur (SrHfS), barium hafnium sulfur (BaHfS), or the like. Further, the gate contact region includes a layer of one of strontium titanium sulfur (SrTiS), barium titanium sulfur (BaTiS), or the like positioned adjacent to the dielectric material layer.
