Classification: CPC H | IPC H

Claim 0:
1. A photodiode, comprising:
a counterdoped heterojunction selected from a group consisting of a pn junction or a p-i-n junction, the counterdoped junction including a first semiconductor doped with an n-type primary dopant and a second semiconductor doped with a p-type primary dopant;
a first counterdoped component selected from a group consisting of the first semiconductor and the second semiconductor being counterdoped, the first counterdoped component being doped with one or more counterdopants that are of a polarity that is the opposite to the polarity of the primary dopant included in the first counterdoped component;
a level of the n-type primary dopant, p-type primary dopant, and the one or more counterdopant being such that the counterdoped junction provides amplification by a phonon assisted mechanism and the amplification has an onset voltage less than 1 V; and
an electrically conducting pinning layer being in contact with the first semiconductor and the second semiconductor.
