Materials Chemist – Soraa. Inc.
Soraa, Inc. is developing technology for low-cost manufacturing of high quality bulk gallium nitride wafers for a range of applications, including light-emitting diodes, laser diodes, and high-performance electronics. Soraas proprietary growth technique, called SCoRA (Scalable Compact Rapid Ammonothermal) combines demonstrated high growth rates with excellent scalability to large volumes. Soraa has funding from a number of sources, including NSF, AFOSR, DOE, and ARPA-E and has full MOCVD and device fabrication capabilities in addition to bulk crystal growth facilities.
Processing and bulk crystal growth of gallium nitride involves highly reactive species and extreme processing conditions but must achieve ultrahigh purity and crystalline quality under cost effective, manufacturable conditions. Meeting these challenges will require knowledge and creative problem solving in the areas of high temperature processes and materials, handling and purification of semiconductor-grade reagents, and thermodynamics. In this position you will work closely with a team of materials scientists, mechanical engineers, chemists, and chemical engineers in an interactive environment to synthesize and characterize GaN crystals and GaN-based materials, develop a quantitative understanding between processing parameters and material quality, and help establish a manufacturing process for high quality bulk GaN crystals.
