Abstract: An embodiment of the invention includes an epitaxial layer that directly contacts, for example, a nanowire, fin, or pillar in a manner that allows the layer to relax with two or three degrees of freedom. The epitaxial layer may be included in a channel region of a transistor. The nanowire, fin, or pillar may be removed to provide greater access to the epitaxial layer. Doing so may allow for a “all-around gate” structure where the gate surrounds the top, bottom, and sidewalls of the epitaxial layer. Other embodiments are described herein.
