Energy is the biggest challenge in the next 50 years. Energy nanotechnology, which combines nanomaterials and nanoscale effects of special properties for specific applications in energy, has become a mainstream campaign of research in the last decade. In this talk, I will present a fewexamples of scanning force microscopy investigations on materials and devices, especially on interfaces in devices. Firstly, a new scanning dielectric force microscopy technique will be introduced and its application in characterization of charge transport properties will be demonstrated. We will then move on to the interfacial dipole measurement in organic photovoltaic device and finally we show force spectroscopy study of SEI (Solid-electrolyte interphase) in lithium ion batteries.
