Abstract

Thin platinum foils and ribbons of the amorphous alloy Fe77Ni1Si9B13 with fractal surfaces made of unidirectional multiscale surface ripples have been prepared. The surface relief and atomic structure of these foils have been investigated by low-energy electron diffraction, atomic force microscopy, and scanning tunnelling microscopy. It has been shown that Pt foils with a fractal surface relief have the prospect for application as reflective diffraction gratings. A model has been proposed and used to calculate the light scattering on unidirectional rippled surface structures of Pt foils.
