Dr. D’Andrade’s expertise is in electrical, electronic, and optical engineering; microelectronic systems; communication network topology, devices, and protocols; and semiconductor materials and devices. He has a decade of experience in the design, failure analysis, and physics of organic light emitting devices that are employed in flat panel displays and solid-state lighting, and over six years of experience in intellectual property related work involving writing patent applications, supporting patent litigation and examining infringing products. His materials science experience includes examining and understanding the fundamental physics of device operation and chemical interactions, in high-vacuum, between organic semiconductors and impurities. His experience in communication networking includes analyses of communication systems used for conducting transactions on public data networks. These analyses involved evaluating communications transactions as handled by the various protocols used in LANs, WANs and private virtual circuits, and the analyses and/or configuration of routers, switches, Ethernet cards and wireless modems. Prior to joining Exponent, Dr. D’Andrade participated in over 12 small business innovation research (SBIR) and solid-state lighting grants from the U.S. Department of Energy as either the principal investigator or the senior scientist. His research interests include: novel device architectures, energy efficient systems, optical outcoupling, organic memories, photovoltaics, printed flexible electronics, lighting design and efficiency, power electronics and smart grid technologies. Dr. D’Andrade has significant experience with ultra-violet photoemission spectroscopy, X-ray photoemission spectroscopy, spectroscopic ellipsometry, time-correlated single photon counting, streak camera temporal spectroscopy, FTIR analysis, cryogenic refrigeration, ultra-high vacuum equipment, organic molecular beam epitaxy, e-beam evaporation, imaging and integrating spheres, sputtering, chemical vapor deposition (CVD), organic vapor phase deposition, spectroradiometers, thermal imaging, encapsulation, and physical vapor deposition (PVD). At Exponent, Dr. D’Andrade has gained an extensive knowledge of GaN, AlGaInP, and ZnSe wide band-gap semiconductors and of non-volatile memory design and processing. His wide band-gap semiconductor knowledge includes: MOCVD and MBE growth methods, doping, and device architectures. His non-volatile memory work focuses on analysis of shallow trench isolation, interlayer dielectrics, spacers, metal contacts and other flash memory structures. Dr. D’Andrade also has investigated failures due to metallic whiskers, printed circuit board design, and faulty capacitors.
