I want to measure the value of metal NP's work function directly. The size of nanoparticle is expected to be below 3nm and dispersed in alcohol based solution.
I heard that there is specific method to determine the work function called as 'Kelvin probe force microscope'.
Here, my question is
1. Can KPFM measure the material submerged in solution?
2. If there are any other way, please recomment the proper solution.
Thank you.
