Senior Principal Scientist and Program Manager, Security and Survivability
Srini Krishnamurthy, Ph.D.,has conducted research on a variety of topics, including:
- Dielectric metamaterials
- Nonlinear absorption and high-intensity light propagation in semiconductors
- Minority carrier and spin relaxation lifetimes in semiconductors
- Modeling of infrared devices, avalanche photodiodes, resonant tunneling devices, power devices, spin field effect transistors, magnetic sensors, and CdTe solar cells
- High-field transport in submicron devices, and optical properties of semiconductors
- Modeling MBE growth
- Empirical and first-principles (LCAO) band structures, and optical, electrical, and electronics properties of semiconductor compounds, alloys, and superlattices
Krishnarmurthy holds bachelor’s and master’s degrees from the Regional College of Education, Mysore, India, and a Ph.D. in physics from the University of Cincinnati. He is an Alexander von Humboldt fellow (Max Planck Institute, Stuttgart 1992, Paul Drude Institute, Berlin, 2001) and a visiting professor of physics at the Indian Institute of Technology-Madras, Indian Institute of Science-Bangalore, and University of Illinois, Chicago.
He has authored or co-authored more than 100 published papers, a book chapter, and a patent.
