Dameng Liu, Lin Wang and Simone Pisana 'Nanohearts'

The photo is a 3D morphology picture obtained with an Atomic Force Microscope (AFM) of a Hafnium Dioxide (HfO2) film. The film was deposited onto crystalline silicon wafer by RF magnetron sputtering with a thickness of 30nm. It's very interesting that the grains' morphology assemble in a heart shape. For this we call the photo "nanohearts". The image is enhanced by Photoshop in which the colour balances were changed to increase the emotional impression.
