Vacancies, traps and defects in chemical electronics

J. (Art) Janata, School of Chemistry and Biochemistry, Georgia Tech

Abstract: Chemically sensitive field-effect transistors (CHEMFET) were first solid state electronic devices for which the name “chemical electronics” was coined. When they started in mid seventies they combined conventional silicon-based electronics with added on “chemistry”. The important facet of this combination was the fact that silicon maintained its primary electronic function while the chemistry took advantage miniaturization, electric field coupling, impedance transformation, etc.. At this interface between solid state electronics and chemistry new types of chemical sensors and devices were born but there has been a price to be paid for these advantages. A much higher level of cleanroom operations, advanced encapsulation and packaging were needed. Personal experience in fabrication, use and testing of these devices will be presented.

Biography: Professor Jiri (Art) Janata is Georgia Research Alliance Eminent Scholar in the School of Chemistry and Biochemistry, Georgia Institute of Science and Technology. Between 1991 and 1997 he was an Associate Director of Environmental Molecular Sciences Laboratory, Pacific Northwest National Laboratory, in Richland, Washington. Prior to that appointment he was Professor of Materials Science and Professor of Bioengineering at the University of Utah for 17 years. He was also Director of HEDCO Microfabrication Facility at the University of Utah.

He was born in Czechoslovakia where he received his Ph.D. degree in analytical chemistry from the Charles University (Prague) in 1965. His current interests include interfacial chemistry, chemical sensors and electrochemistry with particular emphasis on development of chemical sensors for environmental and security applications.
