Photochemistry and other applications of diamond

Diamond is a remarkable material for next-generation electronics and photochemistry applications. The electron affinity of diamond surfaces with H, O, or F termination varies by an astounding 3.5 eV, with hydrogen terminated diamond even possessing a negative electron affinity, meaning that its conduction band minimum lies above the vacuum. Under vacuum, n-type nanocrystalline diamond shows the lowest photo-threshold of any non-cesiated material at 1.5eV. In this project, photostimulated diamond in water is studied for its potential to produce solvated electrons, which can in turn be used for reducing molecules such as N2 or CO2. Other applications of diamond electronics may be discussed if time permits.
