The adhesion behavior of carbon coating studied by re-indentation during in situ TEM nanoindentation

Nanoscale adhesion induced response in terms of re-indentation was directly observed. During unloading (start from B), the re-indentation phenomenon with the displacement sudden drop and the external loading force change from tension (C) to compression (D) within 0.1 s was captured by in situ TEM nanoindentation.
