Abstract: Embodiments include two-dimensional (2D) semiconductor sheet transistors and methods of forming such devices. In an embodiment, a semiconductor device comprises a stack of 2D semiconductor sheets, where individual ones of the 2D semiconductor sheets have a first end and a second end opposite from the first end. In an embodiment, a first spacer is over the first end of the 2D semiconductor sheets, and a second spacer is over the second end of the 2D semiconductor sheets. Embodiments further comprise a gate electrode between the first spacer and the second spacer, a source contact adjacent to the first end of the 2D semiconductor sheets, and a drain contact adjacent to the second end of the 2D semiconductor sheets.
