Title: The Innovations of Pierre Gibart: Pioneering Epitaxial Growth Technologies

Introduction

Pierre Gibart, a notable inventor based in Charcarncuf Grasse, France, has made significant contributions to the field of materials science, particularly in the development of gallium nitride (GaN) technologies. With a portfolio boasting eight patents, his innovative approaches to epitaxial growth have set new standards in the production of high-quality GaN materials.

Latest Patents

Among Gibart's latest patents are groundbreaking processes that enhance the growth of low dislocation density GaN. His first notable patent details a method for producing thick layers of free-standing GaN using a novel modification of the Epitaxial Lateral Overgrowth technology. By manipulating growth parameters, he creates three-dimensional islands during the growth process. This is followed by a smoothing phase that employs two-dimensional growth techniques, leading to a significant reduction in threading dislocation density to below 10 cm.

Another significant contribution is his patented process for producing an epitaxial layer of gallium nitride. This method involves a two-step growth process where the first step focuses on inducing island feature formation under specific growing conditions. Subsequently, the second step enhances lateral growth until coalescence occurs, resulting in a low defect density GaN material.
