Abstract
A photodetector includes a detector material having an upper layer, a lower layer, and at least one sidewall. Also included as part of the photodetector are a first contact electrically coupled to the detector material through the upper layer and a second contact electrically coupled to the detector material through the lower layer. Diffused into the sidewall by a passivation process is a dopant material operable to electrically isolate the first contact from the second contact via the sidewall. The dopant material is provided by a passivation layer deposited on the sidewall.
