Scanning Tunneling Microscopy Helps Monitor Dislocations in Silicene Sheet

People might visualize crystals as perfect structures, but they are usually plagued with “defects.” The interesting fact about these defects is that they often appear as a result of atoms experiencing reorganization to reduce the system’s energy and achieve stability.
