“…Furthermore, thin Pt foils with fractal unidirectional rippled surface relief may serve as a base for manufacturing of reflective diffraction gratings resistant to high temperatures that can operate in a broad range from the infrared to vacuum ultraviolet [4]. Combination of such methods as LEED and AFM permits one to obtain a better judgment on the morphology of surface layers.…”

We investigated the formation of nanostructures on the surface of rolled thin platinum foils at the heating and "tension-compression" cycles in ultrahigh vacuum. The surface was characterized by LEED, AES, AFM, optical microscopy and micro Raman spectroscopy (MRS). Quantitative characterization of the surface relief was made by fractal analysis. About 95 % of the Pt foil surface was made by close packed Pt (111) face with unidirectional rippled multi-scale relief. Under the applied tension, changes in the LEED and AFM patterns were observed and it was found that, preceding the formation of the main crack, the surface becomes difractionally disordered with relief fractality turning to an isotropic one. Moreover, at the foil surface, near the clips of the sample holder (about 5 % of the surface area), the surface groups of micro crystals with sizes about 10 µm were observed which were identified by MRS as microdiamonds and diamond-like carbon.
