Abstract:
1. An article of manufacture comprising: a first insulator region, the first insulator region substantially planar; and a first silicon island formed on the first insulator region and having a first linear dimension substantially parallel to the first insulator region and a second linear dimension substantially perpendicular to the first linear dimension of the first silicon island, the first silicon island having a pillar formed on the first island, the pillar having a first linear dimension substantially parallel to the first insulator region and a second linear dimension substantially perpendicular to the first linear dimension of the pillar, wherein the first and second linear dimensions of the pillar are substantially less than the first and second linear dimensions of the first silicon island, the pillar comprising a p-doped silicon region and an n-doped silicon region, wherein the first insulator region is closer to the p-doped silicon region than to the n-doped silicon region and the first linear dimension of the pillar is not greater than 0.1 microns.
