G.B. Stringfellow

G.B. Stringfellow is a Distinguished Professor in the Departments of Electrical and Computer Engineering and Materials Science and Engineering at the University of Utah's College of Engineering, where he has served since 1980 and previously as Dean from 1998-2003. His pioneering work in semiconductor materials and organometallic vapor phase epitaxy (OMVPE) established foundational principles for multi-billion dollar industries in solar cells and LEDs.

His educational background includes:

• B.S. from the University of Utah
• M.S. and Ph.D. from Stanford University

Stringfellow's research centers on thermodynamics of semiconductor alloys, epitaxial growth mechanisms, and surfactant-mediated processes. He pioneered OMVPE techniques enabling commercial production of energy-efficient optoelectronic devices, with recent work focusing on metastable alloys, quantum dots, and nanowire synthesis for next-generation green energy applications. His investigations into ordering phenomena in III-V semiconductors like GaInP remain highly influential.

Analysis of his 2011-2021 publications reveals sustained innovation in surfactant-controlled growth, doping enhancement, and nanostructure engineering. Key trends include atomic-scale manipulation of InGaN morphology, strain engineering in nanowires, and thermodynamic modeling of phase separation—directly advancing LED efficiency and solar cell technology.

His major scientific honors include:

• National Academy of Engineering election (2001)
• Rosenblatt Prize for Excellence (2004)

Stringfellow has mentored 30 Ph.D. graduates while maintaining exceptional classroom recognition, with students consistently voting him among Utah's top engineering professors. His research program—supported by extensive publications and industry adoption of his methods—demonstrates sustained impact through fundamental science translated into commercial semiconductor manufacturing processes.

His laboratory pioneered OMVPE reactor designs and growth protocols that became industry standards, with current work emphasizing nanoscale control of semiconductor heterostructures for high-brightness LEDs and photovoltaic applications.
