Fig. 3: MoMo adsorption geometry on calcite (10.4).
From: Creating a regular array of metal-complexing molecules on an insulator surface at room temperature
a High-resolution AFM image of MoMo molecules on calcite (10.4) held at room temperature. The molecules are imaged as dark, cross-like structure surrounded by a bright rim. All crosses are oriented in the same direction. b Sketch of the position of the crosses to illustrate the uniform orientation and adsorption site. A calcite (10.4) unit cell is marked with a black rectangle in the bottom left corner. Due to nonlinear thermal drift, a slight deviation between a and b is visible. c Zoom onto two molecules highlighting the cross-like structure. d Top view of thermodynamically most stable MoMo adsorption geometry on calcite (10.4) determined by DFT calculations.
