Abstract
Embodiments described herein include a method for forming a vertical hetero-stack and a device including a vertical hetero-stack. An example method is used to form a vertical hetero-stack of a first nanostructure and a second nanostructure arranged on an upper surface of the first nanostructure. The first nanostructure is formed by a first transition metal dichalcogenide, TMDC, material and the second nanostructure is formed by a second TMDC material. The example method includes providing the first nanostructure on a substrate. The method also includes forming a reactive layer of molecules on the first nanostructure along a periphery of the upper surface. The method further includes forming the second nanostructure by a vapor deposition process. The second TMDC material nucleates on the reactive layer of molecules along the periphery and grows laterally therefrom to form the second nanostructure on the upper surface.
