Our research group is part of the Solid-State Electronics Division at the Department of Electrical Engineering, Uppsala University, Sweden. We are exploring advanced silicon chip technology and new nanodevice concepts towards novel sensing applications for biotechnology and hydorgen safety. We are also interested in new device options for the next generation computing.

In the biotechnology application area, our focus is on novel nanosensor concepts for detection of ions and molecules (such as DNA and protein) with high signal output, low noise and short response time. We are further exploring our nanosensors for biomedical applications of significant societal importance, such as rapid antibiotic susceptibility tests and single molecule/cell analysis to understand cellular and molecular heterogeneities.

For hydrogen safety, we have invented a supersensitive nanotransistor-based gas sensor enabled by electron trapping effect in nanoparticles. A start-up company SweSenSi AB was founded based on this invention.

For the next generation computing, we are exploring high-performance Ag2S based fexible memristors for energy-efficient neuromorphic computing. We are also investigating cryogenic operation of silicon nanodevices for quantum chip applications

Our research activities are sponsored by the Wallenberg Foundation, Swedish Strategic Research Foundation (SSF), Swedish Research Council (VR), Olle Engkvist Foundation，and the Science & Technology Faculty of Uppsala University. We are strongly dependent on the facilities for processing and characterisation provided by Ångström Microstructure Laboratory (MSL) and the other Myfab laboratories. We also contribute to the MSL services by providing expertise competence primarily in semiconductor processing and integration technology.
