  • Abstract
    To obtain a fundamental understanding of the surface processes responsible for the superior emission characteristics of scandate cathodes, a first principles investigation was carried out using the Vienna ab-initio simulation package (VASP) [G. Kresse and J. Furthmuller], a quantum mechanical molecular dynamics simulator.
