Abstract:
1. A semiconductor apparatus, comprising a substrate, the substrate having a first horizontal surface, and an opposite second horizontal surface; at least one elongated 3-dimensional structure that has a length along a path subtending the first horizontal surface and the second horizontal surface, the length being greater than a cross-section of the elongated 3-dimensional structure wherein the cross-section is perpendicular to said path; a first horizontal collection contact electrode on the first horizontal surface; a second horizontal contact electrode on the second horizontal surface; a third horizontal contact electrode on the first horizontal surface; a resistive path provided by the at least one elongated 3-dimensional structure between the third horizontal contact electrode on the first horizontal surface and the second horizontal contact electrode on the second horizontal surface; a second bias between the third horizontal contact electrode on the first horizontal surface and the second horizontal contact electrode on the second horizontal surface for generating a current flow that creates, within the depleted semiconductor material, a constant electric field component that drives signal charge carriers in the depleted semiconductor material in a direction towards the first horizontal collection contact on the first horizontal surface.
