Latest Patents
One of his latest patents is related to a passivation layer for group III-V semiconductor devices. This invention involves forming a passivation layer for a heterojunction bipolar transistor (HBT) from a relatively high bandgap material that is lattice-matched to the HBT components it passivates. By selecting a passivation layer with a higher bandgap than the HBT components, minority carriers are effectively contained within the HBT. The lattice matching ensures a robust bond that prevents the formation of dangling bonds at the exterior surfaces, thereby minimizing surface leakage currents. Another significant patent involves a minority carrier device that comprises a passivating layer including a Group 13 element and a chalcogenide component. This device can include various applications such as laser diodes, light-emitting diodes, heterojunction bipolar transistors, and solar cells.
