Defects on crystal and/or thin film surfaces play an important role in their physical and chemical properties. Diffusion or motion of such structures results in microstructural dynamic changes. The diffusion of single atom/point defects were previously reported, due to the difficulty of observation, the motion of large-scale defects (the defect consist of multiple missing atoms) using combination...
Large areas of nanoscale stripe arrays were produced by drop casting silica nanoparticle solutions on highly oriented pyrolytic graphite surfaces at room temperature and imaged with atomic force microscopy. The alignment of the striped areas always reflected the threefold symmetry of the graphite surface. Two different patterns were observed, with different coverages, line separations and mutual orientation,...
