Abstract

This work is devoted to solving the problem of reducing the work function of a pillared graphene structures. A computational experiment was performed. The purpose was to study various structures of pillared graphene, the cavities of which are filled with potassium. The stability of structures was estimated from the energy of formation, the work function – from the Fermi energy. It was found, that work function decreases with an increase of potassium mass fraction – decrease by 1 eV was reached at 10% mass fraction of potassium and decreasing by 2-2.6 eV has been established at the maximal mass fraction of potassium.
