Keywords: atomic force microscopy; insulating surfaces; Kelvin force probe microscopy; molecular adsorption; Introduction The study of molecular adsorption on atomically clean, well-defined surfaces of bulk insulators is progressing rapidly due to

• combined with NC-AFM [16][17][18][19] to investigate metallic or semiconducting surfaces, as well as adsorbates [20][21] or thin insulating films on metals [18][22][23]. But its application to bulk insulating surfaces [24][25][26] is only beginning, and studies of molecular adsorption on these surfaces are

• due to their high electrostatic energy. They can be stabilized only by charged species, in the present case by adsorption of the negatively charged N atoms of the CN groups. This observation also points to a massive KBr surface mass transfer during the annealing of the substrate due to molecular

• junction and molecular adsorption at the metal electrodes. First, the atomic and molecular motion of the single molecule junction was suppressed in the following order: N2 gas, water, mesitylene, and tetraglyme. This was done in order to reflect the molecular weight and viscosity of the solvent; the

Submonolayer preparations were irradiated with UV light of 266 nm wavelength and the subsequently emerging methyl fragments were probed by

• insight into fundamental issues of the ultrafast reaction dynamics of molecules on metallic surfaces and the influence of organic-molecule–inorganic-substrate interactions on the molecular photoreaction dynamics. Results and Discussion In the following, the results of the molecular adsorption studies and

• ) are almost identical to those of bare Au(111) (Figure 3) in the bias range −1 eV to +1.5 eV, one concludes that STM performed at low bias on 3T/Au(111) senses a Au surface state that is modified by the molecular adsorption. Assuming, similarly to the case of 4-mercaptopyridine (4MPy) on Au(111) [12
