William Hunt

Professor, School of Electrical and Computer Engineering
Director, Microelectronic Acoustics Group

Hunt grew up in the literary haven of Columbus, Mississippi, the boyhood home of Tennessee Williams, and received his B.S.E.E. from the University of Alabama in 1976. He worked for Harris Corporation for two years in the areas of acousto-optics and surface acoustic wave (SAW). He then entered the Massachusetts Institute of Technology where he earned his S.M.E.E. in 1980 and conducted research in the field of auditory physiology. After four years with Bolt, Beranek and Newman, Inc. he entered the University of Illinois, Champaign-Urbana where he received his Ph.D. in electrical engineering in 1987. His research there was on acoustic charge transport (ACT) devices and the SAW properties of Gallium Arsenide.

Hunt joined the faculty of the Georgia Institute of Technology in the fall of 1987 as one of the original members of the Pettit Microsystems Research Center. There he founded the Microelectronic Acoustics Group which focuses on the development of ultrasonic devices that can be integrated with Microsystems. Among these have been, ACT devices, micromachined polyvinylidene fluoride-trifluoroethylene (PVDF)-based transducers for intravascular ultrasound, acousto-optic devices for tunable lasers as well as SAW and bulk acoustic wave (BAW) devices for wireless and chemical sensor applications.

    During my research career I have observed “new” material systems develop and offer promise of wondrous device performance improvements over the current state of the art. Many of these promises have been kept, resulting in numerous new devices that could never have been dreamed of just a few short years ago. Other promises have not been fulfilled, due, in part, to a lack of understanding of the key limitations of these new material systems. Regardless of the material in question, one fact remains true: Without a detailed understanding of the electrical and optical interaction of electronic and photonic “particles” with the material and defect environment around them, novel device development is clearly impeded. It is not just a silicon world! Modern electronic/optoelectronic device designs (even silicon based devices) utilize many diverse materials, including mature dielectrics such as silicon dioxide/nitrides/oxynitrides, immature ferroelectric oxides, silicides, metal alloys, and new semiconductor compounds. Key to the continued progress of electronic devices is the continued development of a detailed understanding of the interaction of these materials and the defects and limitations inherent to each material system. It is my commitment to insure that new devices are continuously produced based on complex mixed family material systems.
