Abstract
A surface with a low work function is formed from a starting material of diamond or diamond-like carbon. An oxygenation treatment is performed, so that the surface of the diamond or diamond-like carbon is oxygenated. Lithium is then deposited onto the oxygenated surface by means of a physical vapour deposition process. Excess lithium is then removed to form a lithium monolayer.
