Fig. 2: STM image and model structure of phase I film.
From: Enhanced magnetic spin–spin interactions observed between porphyrazine derivatives on Au(111)
a Magnified STM image of phase I film of VOTTDPz monolayer film (Vs = −0.8 V, It = 160 pA). Crystallographic direction of Au substrate is indicated by an arrow. Length bar (grey line) is 1 nm. b Top view of the adsorption model. Green parallelogram (unit vectors s and t) corresponds to the unit cell containing two molecules, corresponding to the one in a with white lines. c Side view of the same model of b. d Height profile vs. horizontal distance along two symmetry lines in the lower panel, whose lines are superimposed in the upper topo image with the same color.
