Viktor O. Semin, 30 years old (14.05.1992, born in Tomsk, Russia). Research fellow in the Institute of Strength Physics and Materials Science SB RAS, Tomsk, Russia Young carrier experimental researcher in condensed matter physics and materials science defended PhD in 2018 (19th of October) in the Institute of Strength Physics and Materials Science (ISPMS) Siberian Branch of Russian Academy of Sciences, Tomsk, Russia. Almost 6 years V. Semin have been mastering JEOL JEM 2100 transmission electron microscope and performing materials characterization by means of X-ray diffraction and Auger electron microscopy. The most relevant research achievements during the last 5 years (the total number of publication is 20, including 15 papers published in the Q1, Q2 rank journals) can be summarized: Advances in materials characterization by laboratory TEM and XRD methods including foil preparation (thin films, powders and bulk materials) by ion-beam technique. Operation with specialized software (Quantum EXPRESSO, VESTA, ToposPRO, PDFgui, Digital Micrograph scripts) for crystallographic tasks and diffraction issues. Development of a methodology for studying amorphous and quasicrystalline alloys, namely, transmission electron microscopy (TEM) methods; Determination the nature of chemical and topological short- and medium-range order in amorphous alloys characterized by a gradient chemical composition during low-temperature annealing.
