Modeling of thermal treatment of copper nanoparticles synthesized from gaseous phase


I.V. Chepkasov - Ph.D. (Phys.-Math.), Khakas State University, Abakan. E-mail:

By molecular dynamics method with the use of strong coupling potential the thermal impact on copper nanoparticles synthesized from gaseous phase was simulated. It was established that cluster heating up to temperature 300…500 K, further structural ordering to 55…60 %, and at T = 600 K the long-range order disappeared. At 1100 K the complete melting of the nanoparticle was observed. It was shown 70%. The rest part of 30% clusters did not reduce to common structure shape and structure in the process of thermoactivated relaxation.
