Jian V. Li holds a PhD in electrical engineering from the University of Illinois at Urbana-Champaign, USA. Since 2017, he has been an associate professor at National Cheng Kung University, Taiwan. He specializes in the characterization of semiconductor materials and devices—especially properties concerning defects, carrier recombination, and interfaces—with capacitance spectroscopy and other electrical–optical techniques. Giorgio Ferrari obtained his PhD in electronics engineering in 2003 from the Politecnico di Milano, Italy. Since 2005, he has been an assistant professor of electronics at the Politecnico di Milano. His research concerns the development of novel integrated instrumentation to probe electrical properties of materials, devices, and biosamples at the nanoscale.
