Ellipsometry examination of copper alloys with transitive metals

Filipov, Y.V.; Staschuk, V.S.; Poperenko, L.V.; Vovchenko, V.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2004)

Electron structure of copper alloys with 3d transition metals (Fe, Co and Cr) have been studied basing on elliposometrical measurement of D and Y in wide spectral range hn = 1.0–4.95 eV. Spectral dependences of Cu-Cr alloys ...
Energy loss researches of diamond microgrinded laser mirrors by Fourier optics methods

Staschuk, V.S.; Kononchuk, G.L.; Poperenko, L.V.; Stukalenko, V.V.; Filipov, Y.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2009)

The diffraction losses of laser mirrors were determined by using specially designed spectrometer of spatial frequencies. Reflection surface (70 mm diameter) was made by diamond microgrinding, but instead of an ideal ...
Formation of blisters in thin metal films on lithium niobate implanted by keV Ar⁺ ions
