Latest Patents

One of her latest patents is for a "Laser diode with improved heat dissipation." This innovative laser diode structure includes two different insulator layers, one designed to maintain good optical confinement, typically located at the sides of the laser ridge, and another to enhance heat dissipation properties, typically positioned on the etched surfaces away from the ridge. Another notable patent is for the "MBE growth of a semiconductor layer structure." This method involves growing a first (Al,Ga)N layer over a substrate at a specific temperature using ammonia as the nitrogen precursor. The substrate is then cooled to a lower temperature, followed by the growth of an (In,Ga)N quantum well structure, also using ammonia. This continuous supply of ammonia during the growth steps ensures optimal conditions for the semiconductor layers.
