Abstract We report a combined experimental and theoretical study of the modulation of surface charge transfer on the TTF [tetrathiafulvalene]/Au(111) interface as a function of coverage in the submonolayer regime by combining low-temperature scanning tunneling microscopy, high resolution photoemission spectroscopy using synchrotron radiation and density functional theory (DFT) calculations. The modulation is induced by the competition between long-range repulsive Coulombic interactions and short-range attractive hydrogen-bonding interactions. The system shows the characteristic pattern evolution, from monomeric stripes at low coverages to two-dimensional islands, with the formation of labyrinths in the crossover.
