ABSTRACT:
A heterojunction semiconductor is provided where the carrier transport dimension is governed by a layer thickness and where the characteristics of the materials self-limit process steps. A field effect transistor is provided wherein the work function is matched across regions to reduce limits on the channel dimension. A vertical transistor is provided wherein a vertical web is formed with precise thickness governed by electrolytic etching using photogenerated carrier current.
