Professor Emeritus Lew Reynolds retired from the department in 2023. He was the Graduate Distance Education Coordinator, Director of the Nanoengineering Graduate Program, and a Teaching Professor. Reynolds was a Distinguished Member of Technical Staff at Bell Laboratories for 23 years prior to coming to NCSU in 2003. He has 30 years of experience in the growth, characterization, and device development of III-V compound semiconductors. He has investigated extensively the influence of doping profiles on laser characteristics, developed MOVPE growth techniques for growth on gratings and along mesa sidewalls to minimize defects, and collaborated on the design of high-speed photonic devices. More recent efforts have focused on mobility modulation in AlGaN HFET structures, strain relaxation in InGaAs solar cell structures, characterization of GaAsSb nanowires for mid-IR applications, and the pulse width dependence of optical gain in conjugated polymers.

Reynolds has been issued eight U.S. patents. His research interests are compound semiconductor materials and devices, electrical and optical properties, thin film epitaxial growth of group III-nitrides and group II-oxides, heteroepitaxy, strain relaxation in misfit systems, defects and interfaces, quantum well structures, electronic and photonic devices, optical properties of conjugated polymers, and nanostructured materials.
