    Abstract: A vertical field effect device includes a substrate and a vertical channel including InxGa1-xAs on the substrate. The vertical channel includes a pillar that extends from the substrate and includes opposing vertical surfaces. The device further includes a stressor layer on the opposing vertical surfaces of the vertical channel. The stressor layer includes a layer of epitaxial crystalline material that is epitaxially formed on the vertical channel and that has lattice constant in a vertical plane corresponding to one of the opposing vertical surfaces of the vertical channel that is greater than a corresponding lattice constant of the vertical channel.
