摘要: Subtle changes in the geometric and electronic properties of supported molecules, with a potential impact on functioning molecular devices, can typically be imaged by scanning probe microscopy, but their exact origin nature often remain unclear. Here we show explicitly that symmetry reduction iron phthalocyanine upon adsorption Cu(111) observed not only tunneling also core-level spectroscopy, it is related to nonisotropic charge transfer into two principal axes, combination topographic influences.
