We found monochromatic electron photoemission fromlarge-area self-assembled monolayers of a functionalized diamondoid,[121]tetramantane-6-thiol. Photoelectron spectra of the diamondoidmonolayers exhibited a peak at the low-kinetic energy threshold; up to 68percent of all emitted electrons were emitted within this single energypeak. The intensity of the emission peak is indicative of diamondoidsbeing negative electron affinity materials. With an energy distributionwidth of less than 0.5 electron volts, this source of monochromaticelectrons may find application in technologies such as electronmicroscopy, electron beam lithography, and field-emission flatpaneldisplays.
