Title
Nanoparadise
Technique
Atomic Force Microscopy-Kelvin Probe Force Microscopy (KPFM) mode.
Description
On this image you can see ferroelectric thin film of barium titanate (BTO) partially functionalized with self-assembled layer of aminobenzoic acid (ABA) molecules. Kelvin Probe Force Microscopy enabled us to differentiate between pristine BTO thin film (blue) and ABA molecular layer attached to BTO (yellow) based on the difference in their work functions and without perturbing the surface since all the measurements are done in non-contact mode. Doesn´t it remind you of perfect summer landscape – ocean with couple of islands?
