Title: Alexander Usikov: Innovator in Indium Nitride Growth Technologies
Introduction
Alexander Usikov is a prominent inventor based in Gaithersburg, MD (US). He holds a total of 8 patents that showcase his contributions to the field of materials science, particularly in the growth of indium nitride.
Latest Patents
His latest patents include innovative technologies such as the "HVPE apparatus and methods for growing indium nitride and indium nitride materials and structures grown thereby." This hydride phase vapor epitaxy (HVPE) growth apparatus features generation, accumulation, and growth zones. The reactor generates and collects a source material for the growth of indium nitride. A first reactive gas reacts with an indium source to produce a gas product containing an indium compound, which is then cooled and condensed into a source material. The vapor resulting from evaporation forms a second gas product that reacts with another reactive gas for the growth of indium nitride. Another significant patent is focused on "Apparatus and methods for controlling gas flows in a HVPE reactor." This technology utilizes a gas focusing element and a multi-tube structure to manage gas flows effectively, ensuring optimal conditions for the growth of group III nitride materials.
