Laser irradiation of 10×(Ni/Ti)/Si multilayers at different wavelengths

X-ray diffraction study of laser-driven solid-state diffusional mixing and new phase formation in Ni-Pt multilayers

“…This electron plasma very rapidly diffuses through the metal and thermalizes with the atomic lattice on picosecond timescales 9,10 . Pulsed laser systems can generate temperature jumps in solids well in excess of 1000K [11][12][13] . Previous studies integrating pulsed laser excitation with small angle x-ray scattering techniques have provided direct evidence of optically driven atomic diffusion solid state systems 14,15 .…”
