His primary research interest is in modeling and simulation of physical phenomena in the field of microelectronics.
Since 1988 Siegfried Selberherr is a chair professor for software technology of microelectronic systems at the TU Wien.
Between 1996 and 2020 Prof. Selberherr was a Distinguished Lecturer of the IEEE Electron Devices Society.
In his scientific career Prof. Selberherr has published, with his teams of researchers, so far over 400 journal papers and over 1200 articles in conference proceedings, of which more than 250 have been with an invited talk.
During his research work Prof. Selberherr has developed a simulator for 'Metal-Oxide-Semiconductor' devices (MINIMOS), in which a mobility model for charge carriers is implemented, which is named after him.
