Patent ID: 6881979

Claim:
An optoelectronic device, comprising: a first ohmic contact on a first surface of a silicon wafer and a second ohmic contact on a first area of a second surface of the silicon wafer; an aluminum nitride layer deposited on a second area of the second surface of the silicon wafer, a portion of the aluminum nitride having diffused into the silicon layer to form a p-n junction in the silicon wafer; a first layer of gallium nitride deposited on the aluminum nitride layer; a layer of indium gallium nitride deposited on the first layer of gallium nitride, the layer of indium gallium nitride having a top surface; a second layer of gallium nitride deposited on a first area of the top surface of the indium gallium nitride layer and an ohmic contact on the second layer of gallium nitride; and a second ohmic contact on a second area of the top surface of the layer of indium gallium nitride.
