ͼƬ˵Ã÷£ºFIG. 5. (Color online) Calculated Hartree potential profile of a
stoichiometric TiO2-water slab system. The vertical green dashed line
indicates the interface. The left side is semiconductor TiO2 and the
right side is water. The black solid line is the planar-averaged Hartree
potential as a function of cell dimension normal to the interface. The
red dashed line with square markers indicates the planar-averaged
Hartree potential of TiO2, Hsemi edge. The blue dashed line with
circular markers indicates the planar-averaged Hartree potential of
liquid water, Hsol edge.
