Implementation of ACRT in Czochralski growth of Doped Single Crystals from Melt
Unmet Need: Homogeneous doping is hard to achieve by traditional methods Crystal growth using conventional methods such as Czochralski (CZ), often suffer from core breakdown and low uniformity. This was shown especially for those crystals grown with low temperature gradients and those grown from highly viscous melts, in which natural convection does...

Micro Heat Engine/Refrigerator
Abstract WSU inventors have developed micro-transducers with piezoelectric properties for converting energy in one form to useful energy in another form. Piezoelectric thin films have been used for years as power transducers in micro-electro-mechanical systems (MEMS) and micro-electronic devices. Piezoelectric films are an attractive option for power...

Growth of Cerium Doped Yttrium Aluminum Garnet from an Alumina Rich Melt
Abstract This WSU invention concerns the growth of Cerium Doped Yttrium Aluminum Garnet (Ce:YAG) from a melt containing aluminum oxide with known amounts of YAG. Ce:YAG is a phosphor, when in its pure single-crystal from, with a wide range of uses. Notably, crystals can be used in white light-emitting diodes, as a coating on a high-brightness blue Indium...

Method of overcoming electrostatic repulsion when storing large densities of charged particles such as positrons
Abstract WSU inventors have developed a prototype trap that can store significant quantities of positrons that can create a tremendous amount of energy. Particles of antimatter, positrons, probes the basic interactions and properties of matter and has broad potential applications, including development of a new and high quality computer microchips,...
