| dc.description.abstract | Ultrashort laser irradiation is proven as an alternative to lithography for nanostructuring surfaces of various materials via formation of laser-induced periodic surface structures (LIPSS) or ripples. In this work, our efforts were focused on the study of LIPSS formation with the periodicity of the order of laser wavelength on surfaces of Ge2Sb2Te5 (GST225) amorphous thin films. GST225 composition is one of the extensively investigated phase change memory (PCM) materials, which is currently used for rewritable data storage applications based on structural phase transitions. In addition, we studied the processes of laser crystallization and laser amorphization of GST225 thin films under ultrashort pulsed irradiation. | en_US |
