Elliott Brown is a Professor of Physics and Electrical Engineering at Wright State University.  Previously he was Professor of Electrical and Computer Engineering at the University of California, Santa Barbara and Los Angeles campuses.  A hallmark of Dr. Brown’s career has been the transition of novel materials and devices into useful instruments and systems.  This includes THz photomixing sweep oscillators, photomixing and time-domain spectrometers, and new pulsed THz imaging systems. These have enabled several new applications such as identification of absorption signatures in bio- and organic materials (e.g., opioids), and the transmission and reflection from human tissue. Dr. Brown’s group also works on RF and biomedical sensor systems achieved by multifunctional integration or by the integration of RF components with devices from other physical domains.  His current biomedical research addresses the use of THz radiation to image the cornea, burns, cancers and other lesions in human skin using a novel impulse radar developed originally with the UCLA School of Medicine and more recently Aalto University in Finland.

Before joining UCLA Prof. Brown was a Program Manager at DARPA (Electronics Technology Office) in Arlington, VA where he helped create and execute programs in advanced RF technology (MAFET Thrust 3), high-power solid-state electronics (Megawatt), highly-controlled infrared dielectric emissivity (HIDE), and advanced ultrasonic imaging technology (Sonoelectronics).  Prior to DARPA Dr. Brown was an Assistant Group Leader and Staff Researcher at MIT Lincoln Laboratory in Lexington, MA.  While at Lincoln Lab he conducted original research and development in advanced electromagnetics, ultrafast electronics and optoelectronics, solid-state device physics, and high-frequency receiver technology.  Among his key inventions and discoveries were the photonic-crystal planar antenna, the low-temperature-grown-GaAs THz photomixer, the resonant-tunneling-diode relaxation oscillator, normal-incidence absorption in semiconductor quantum wells, and shot-noise suppression and quantum-transport inductance in resonant-tunneling devices.  Each of these has been unique in terms of device performance or scientific contribution.  For example, the photonic-crystal planar antenna was the first RF application that utilized the three-dimensional nature of the photonic stop bands, and has helped point a new direction in monolithic integrated circuits whereby the semiconductor substrate can be fabricated to improve rather than degrade the performance of passive RF components.

Dr. Brown received his Ph.D. and Master’s degrees in Applied Physics in 1985 and 1981, respectively, from the California Institute of Technology where he conducted research on mm-wave-to-THz mixers made from semiconductor hot-electron bolometers under magnetic quantization.  He received his B.S. degree in Physics from UCLA in 1979.  During the period of 1977 to 1981, he received Fellowships at the Hughes Aircraft Company where he worked on key components in mm-wave radiometers and high-speed (> 1Gb/s) laser communications systems for the Space and Communications Group, El Segundo, CA.

Teaching

Dr.  Brown has taught courses in solid-state engineering and physics, sensor physics, THz science and technology, electromagnetic fields and waves, antenna engineering, RF sensors and engineering principles of ultrasound

Research Statement

Dr. Brown's primary area of research is THz technology and science, including new THz photoconductive materials and devices for 1550-nm pump lasers, ultra-efficient 1550-nm photoconductive switches, quantum-optical (superradiant) emitters, and new passive components based on surface-structured plasmonics. He discovered the superradiant emitters in dense arrays of ErAs quantum dots embedded in GaAs, which display a wealth of interesting materials science and electron transport effects as well, including an insulator-to-metal phase transition.

His second area of research is quantum transport devices, especially n-type resonant-tunneling diodes (RTDs) which have been an area of expertise since his postdoctoral research in the 1980s.  The initial focus was on demonstrating RTDs as room-temperature THz oscillators, which led to a demonstration up to 712 GHz in 1990 – a record high frequency which has only been been eclipsed in the past 10 years.  More recently his focus has shifted to the development of RTDs in alternative material systems, such as GaN/AlN, for which his team demonstrated the first room-temperature, reproducible operation in 2016.  Besides fast oscillation and switching, they also discovered strong band-edge electroluminescence from both GaN/AlN and In0.53Ga0.47As/AlAs RTDs, and have associated the emission with hole generation created by interband tunneling.  Hence, they have proven that RTDs can exhibit two types of tunneling simultaneously – resonant-intraband and non-resonant interband tunneling, which together produce a useful room-temperature light emission

Service

Dr. Brown  has served on numerous committees, mostly at the graduate level, such as the Physics Graduate Admissions Committee.  He has also served on the Ph.D. in Engineering Committee, and the Interdisciplinary Applied Science and Mathematics (IASM) Committee.
