ABSTRACT:
A diode comprises a substrate formed of a first material having a first doping polarity. The substrate has a planar surface and at least one semispherical structure extending from the planar surface. The semispherical structure is formed of the first material. A layer of second material is over the semispherical structure. The second material comprises a second doping polarity opposite the first doping polarity. The layer of second material conforms to the shape of the semispherical structure. A first electrical contact is connected to the substrate, and a second electrical contact is connected to the layer of second material. Additional semiconductor structures are formed by fabricating additional layers over the original layers.
