Abstract
An article of manufacture and a method of defining a photodetector element are provided. The article of manufacture includes a photodector element comprising a junction formed by a first III-V semiconductor layer having a first charge type and a second III-V semiconductor layer comprising a second dopant having a second charge type. The second III-V semiconductor layer is disposed between the first III-V semiconductor layer and a wafer. Patterned dopant regions having a third charge type, the third charge type being the same as the first charge type, are disposed in the first III-V semiconductor layer.
