Abstract
In situ atomic force microscopy observations of nickel thin films on substr ates under external compressive stresses have been carried out. Straight-si ded wrinkles arise perpendicularly to the compression axis above a critical stress and undulations of very low amplitude also appear on these debondin g regions. The dependence on stress of the shape of the wrinkles and of the undulations is discussed.
