An optoelectronic device comprises a photodetector feature, an interfacial layer disposed above at least a portion of the photodetector feature, and a vertical contact disposed on at least a portion of the interfacial layer. The photodetector feature comprises germanium and is operative to convert a light signal into an electrical signal. The interfacial layer comprises nickel. Finally, the vertical contact is operative to transmit the electrical signal from the photodetector feature.
