Data on Solid State Physics Detailed by Researchers at Goethe-University (Simulation of nanowire fragmentation by means of kinetic Monte Carlo approach: 2D case)

By a News Reporter-Staff News Editor at Physics Week -- Investigators publish new report on Solid State Physics. According to news originating from Frankfurt, Germany, by VerticalNews correspondents, research stated, "In the present paper, the evolution over time of flat nanowires (NWs) with different widths and at different temperatures is simulated by computer modeling and analyzed. The results can be applied to a wide range of physical systems as the NWs could be parts of nanoelectronic devices or nanosystems, e. g., nanofractals, which can be created during the deposition of nanoparticles on surfaces."

Our news journalists obtained a quote from the research from Goethe-University, "The present paper deals with the initial stages of nanowire evolution aiming at the elucidation of the essential features of the fragmentation process. It is demonstrated that the breakup of NWs is driven by the diffusivity of the particles at periphery. The microscopic parameters characterizing the fragmentation are established. The dependence of the time required for the first fragmentation on the nanowire width is presented. The temperature dependence of the nanowire fragmentation is also examined. The dependences of the maximum number of islands created in the fragmentation process on the nanowire width and the temperature are derived."

According to the news editors, the research concluded: "Examination of the temperature dependence of the first fragmentation instant and number of islands as well as the dependence of these quantities on the nanowire width gives the possibility to establish the relationships between experimental observations and microscopic parameters of the system."
