About Professor Iyer

Prof. Iyer has been responsible for the initiation and development of NC A&T SU’s state of the art Molecular Beam Epitaxy (MBE) Laboratory and associated academic and research programs. She has been a PI of over $10 million in DoD research projects. She was also the Director of the Center of Excellence for Battlefield Capability Enhancements, which focused on developing technologies for environmentally stable flexible panel displays.

Her current research interests are in the molecular beam epitaxial (MBE) growth, characterization and fabrication of GaAsSb(N) nanowire based infrared photodetectors epitaxially integrated to Si and graphene for next generation photonic devices. This research is cross-disciplinary encompassing solid state physics, nanoengineering, and optoelectronic devices.
