For more than 30 years, SOI materials and device have been important research directions in-SIMIT. To meet the “More than Moore” demands for future technology, advanced devices such as high-mobility transistor, quantum-well-MOSEFT and TFET based on SOI substrate have become promising candidates. The cooperation on SOI material and device between SIMIT and Jülich has lasted about 10 years. With state of the art research tools, a group of young researchers from SIMIT carried out their work in Jülich to improve the SOI technologies. Representative results have been published in top international journals such as IEEE TED, IEEE EDL and APL, etc. In the past ten years, there are 6 exchange PhD students and scholars between Jülich and SIMIT.
