Dr. Andrei L. Kholkin is a Principal Researcher at the CICECO-Aveiro Institute of Materials and Department of Physics at the University of Aveiro in Portugal. Dr. Kholkin’s research interests are in the area of materials science of ferroelectrics, piezoelectrics, and multiferroics: thin films, single crystals and ceramics. His study is mainly devoted to functional materials for piezoelectric devices, degradation effects, and, recently, to their nanoscale characterization by Scanning Probe Microscopy techniques.
