Title: The Innovations of Michael D. Craven
Introduction
Michael D. Craven is a prominent inventor based in Goleta, California. He holds a total of 11 patents, showcasing his significant contributions to the field of materials science and engineering. His work primarily focuses on non-polar gallium nitride (GaN) and its applications in quantum wells.
Latest Patents
One of his latest patents is titled "Non-polar (Al,B,In,Ga)N quantum wells." This patent describes a method of fabricating non-polar a-plane GaN/(Al,B,In,Ga)N multiple quantum wells (MQWs). The a-plane MQWs are grown on appropriate GaN/sapphire template layers via metalorganic chemical vapor deposition (MOCVD), with well widths ranging from 20 Å to 70 Å. The room temperature photoluminescence (PL) emission energy from the a-plane MQWs follows a square well trend modeled using self-consistent Poisson-Schrodinger (SCPS) calculations. Optimal PL emission intensity is achieved at a quantum well width of 52 Å for the a-plane MQWs. Another significant patent is "Non-polar gallium nitride thin films grown by metalorganic chemical vapor deposition." This patent details the growth of non-polar (110) a-plane gallium nitride (GaN) films with planar surfaces on (102) r-plane sapphire substrates, employing a low-temperature nucleation layer as a buffer layer prior to high-temperature growth.
