报告摘要：
Atomic force microscope (AFM) has become a quintessential tool for exploring nanoscale material properties. Specifically the last few years have witnessed a revolution of the capabilities offered by AFM to explore local physical phenomena at the nanoscale. In this presentation, I will present how material properties can be measured using AFM and, furthermore, summarize our recent effort on the development of the AFM techniques and application of advanced AFM techniques for exploring various local physical phenomena, e.g. piezoelectricity in 2D MoTe2, ferroelectricity in CH3NH3PbX, BiFeO3 and HfO2, and electrochemistry in carbon and advanced high strength steels. In addition, I will briefly discuss how we were able to tune material properties through point defect engineering.
