Brian Bennett awarded as a fellow of the American Physical Society

His important contributions in materials physics over the last two decades include electro-optical effects in III-V compound semiconductors and as well as self-assembled quantum dots

Brian Bennett, a scientist at the Naval Research Laboratory is recognised by APS "for pioneering contributions to the epitaxial growth, characterisation, and design of narrow band-gap semiconductor heterostructures."

His primary focus over the last several years has been in the design, growth, and characterisation of antimonide-based semiconductor heterostructures for application to high-frequency, low-power electronics. Bennett's research (in collaboration with J. Brad Boos and colleagues) has established the Naval Research Laboratory as one of the world leaders in this field. His efforts on the design and epitaxial growth of high-electron mobility transistors based upon InAs quantum wells and antimonide barriers helped to develop a technology which was transferred to industry, leading to the production of low-noise amplifiers operating at ultra-low-power for DoD applications.

Bennett received his bachelor's degree (1984), master's degree (1985), and doctorate (1992) all from the Massachusetts Institute of Technology. He served as a military officer in the U.S. Air Force's Solid-State Sciences Division from 1984 to 1988. 

He has been at NRL since 1992 and currently serves in the Electronics Science and Technology Division as head of the Nanotechnology Section, which includes 12 PhD scientists working on topics including graphene, carbon nanotubes, quantum wires, atomic layer deposition, and plasmonics. 

Results of his research have been reported in over 160 archival journal publications and cited over 5,000 times. He also holds ten U.S. patents. Bennett has served as an organiser and/or committee member of Electronic Materials Conference since 2000.

Bennett has been recognised with an NRL Technology Transfer Award in 2001; an NRL Group Achievement Award in 2004 for successful transition of antimony based HEMT technology developed at NRL to Northrop-Grumman Space Technology; an NRL Edison Patent Award in 1998 and 2009; an NRL Berman Publication Award in 1998, 2000, and 2008; and a Navy Top Scientist/Engineer of the Year Award (one of 18 out of 35,000 eligible) in 2009.
