Title: The Innovative Contributions of Laurence A Gea
Introduction
Laurence A Gea is a notable inventor based in Knoxville, TN (US). He has made significant contributions to the field of materials science, particularly in the development of optical surfaces. His work focuses on the formation of vanadium dioxide precipitates, which have unique properties that can be utilized in various applications.
Latest Patents
Gea holds a patent for a method titled "VO.sub.2 precipitates for self-protected optical surfaces." This patent describes a process for forming crystallographically coherent precipitates of vanadium dioxide in the near-surface region of sapphire. The method involves stoichiometrically implanting ions of vanadium and oxygen into a sapphire substrate (Al.sub.2 O.sub.3) and subsequently annealing it to create vanadium dioxide precipitates. These embedded VO.sub.2 precipitates are three-dimensionally oriented with respect to the crystal axes of the Al.sub.2 O.sub.3 host lattice. They undergo a first-order monoclinic-to-tetragonal phase transition at approximately 77 degrees Celsius. This transformation results in a significant variation in the optical transmission of the implanted region, leading to the formation of an optically active, thermally 'switchable' surface region on Al.sub.2 O.sub.3.
