Abstract
Semiconductor devices includes a thin epitaxial layer (nanotube) formed on sidewalls of mesas formed in a semiconductor layer. In one embodiment, a semiconductor device includes a first semiconductor layer, a second semiconductor layer formed thereon and of the opposite conductivity type, and a first epitaxial layer formed on mesas of the second semiconductor layer. An electric field along a length of the first epitaxial layer is uniformly distributed.
