Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. The avalanche diode of claim 1, wherein:
when the diode experiences depletion, the reverse bias electric field, a first n-type dopant density in the n+-type region and a second p-type dopant density in the p+-type region are in a range that achieves gain using impact ionization in the p-n junction without breakdown of the p-n junction; and
a second n-type dopant density in the n-type region and a second p-type dopant density in the p-type region are in a range such that:
the reverse bias electric field does not induce impact ionization in the n-type region or the p-type region,
the second p-type dopant density enables saturation of the drift velocity in the p-type region, and
the second n-type dopant density enables saturation of the drift velocity in the n-type region.
