Erik Kollberg

Professor emeritus at Chalmers, Microtechnology and Nanoscience (MC2), Terahertz and Millimetre Wave Laboratory

Erik L. Kollberg was born in Stockholm in 1937. In 1970 he received his PhD at Chalmers University of Technology, in Göteborg, Sweden. In 1979 he became full professor at Chalmers. From 1967 to 1987 he was the head of the group developing low noise receivers for the Onsala Space Observatory telescopes. He was acting Dean of Electrical and Computer Engineering 1987-90. In 1995 he founded Chalmers center for high speed electronics (CHACH). He has been performing research on millimeter wave and submillimeter wave devices and low noise receivers including maser amplifiers, Schottky diode and SIS mixer receivers. He has also worked on harmonic multipliers and is the inventor of the heterostructure barrier varactor diode. His present main research interests are in the areas of millimeter wave and THz devices and applications, in particular hot electron bolometer mixers. Prof. Kollberg and his group received the 1982 Microwave Prize given at the 12th European Microwave Conference in Helsinki, Finland. In 1983-84 he chaired the MTT Chapter in Sweden. He has been a guest professor at Ecole Normal Superieure, Paris, France and at California Institute of Technology. The year 2000 he was awarded an Honorable Doctorate at the Helsinki University of Technology. He is a member of the Royal Swedish Academy of Science and the Royal Swedish Academy of Engineering Sciences.
