A. Nagashima et al., ELECTRONIC STATES OF THE HETEROEPITAXIAL DOUBLE-LAYER SYSTEM - GRAPHITE MONOLAYER HEXAGONAL BORON NITRIDE/NI(111)/, Physical review. B, Condensed matter, 54(19), 1996, pp. 13491-13494
By using angle-resolved ultraviolet photoelectron spectroscopy, x-ray
photoelectron spectroscopy, and work function measurement, we have exp
lored the electronic states of the heteroepitaxial double-layer (HEDL)
system composed of Ni(111), monolayer hexagonal boron nitride, and gr
aphite overlayer. Present data clearly indicate that in the HEDL syste
m, the spatial change of the electronic states at the interfaces is ab
rupt in atomic scale.
