Extremely high negative electron affinity of diamond via magnesium adsorption

We report large negative electron affinity (NEA) on diamond (100) using magnesium adsorption on a previously oxygen-terminated surface. The measured NEA is up to (-2.01±0.05) eV, the largest reported negative electron affinity to date. Despite the expected close relationship between the surface chem...
