Latest Patents

One of his latest patents is titled "Epitaxial metallic transition metal nitride layers for compound semiconductor devices." This patent describes a method for integrating epitaxial, metallic transition metal nitride (TMN) layers within a compound semiconductor device structure. The TMN layers exhibit a crystal structure similar to relevant semiconductors, such as silicon carbide (SiC) and the Group III-Nitrides (III-Ns) like gallium nitride (GaN), aluminum nitride (AlN), and indium nitride (InN). These layers demonstrate excellent thermal stability and can be deposited in situ with other semiconductor materials, allowing them to be embedded within the semiconductor device structure to create semiconductor/metal/semiconductor heterostructures and superlattices.

Another notable patent is the "Method for reducing the concentration of oxygen, carbon, and silicon impurities on nitrogen-polar surfaces of gallium nitride." This method involves preparing GaN material by subjecting a GaN substrate to multiple cycles of Ga deposition and desorption, followed by applying a layer of AlN to the substrate. This process results in reduced concentrations of impurities, enhancing the quality of the GaN material.
