Water chemistry on surfaces

Ion solvation

Our lab has a custom-built high-pressure atomic force microscope (HP-AFM) which can probe surfaces in a wide pressure range from UHV to 1 bar. This is an ideal tool for investigating the pressure-dependent solvation of atomically-flat and nano-structured ionic materials such as alkali halides and halide perovskites. The tecnique is multi-functional, namely, it can be used to map the topography while probing a material property, such as the relative work function, surface conductance, frictional properties, etc. It can also be operated in contact, non-contact, and intermitted-contact modes.
