This section gives a quick (and incomplete) overview of what ASE can do. We will calculate the adsorption energy of a nitrogen molecule on a copper surface. This is done by calculating the total energy for the isolated slab and for the isolated molecule. The adsorbate is then added to the slab and relaxed, and ...
