Nanostructuring of potassium fulleride layers

Homogeneous \chem{C_{60}} layers are prepared by vapor deposition. Electrochemical doping with \chem{K^{+}} ions leads to the formation of nanostructures on a 20\un{nm} to 50\un{nm} scale. It is shown by means of Monte Carlo simulations that this process can be understood as a decomposition of \chem{K} x \chem{C_{60}}, 0.1<{x}<3, with respect to the distribution of the \chem{K^{+}} ions and subsequent local phase transformations into α-\chem{C_{60}} regions and \chem{K_{3}C_{60}} clusters. The metallic \chem{K_{3}C_{60}} clusters are used as electrodes for nanometre-scale metallization of the layers
