    Phase changes in icosahedral 54-, 55-, 56-atom platinum clusters
    (World Scientific Publ Co Pte Ltd, 2004) Sebetci, A; Güvenç, Ziya Burhanettin; Güvenç, ZB; Kökten, H; Bilgisayar Mühendisliği
    Using the Voter and Chen version of an embedded-atom model, derived by fitting simultaneously to experimental data both the diatomic molecule and bulk platinum, we have studied the melting behavior of free, icosahedral, 54-, 55- and 56-atom platinum clusters in the molecular dynamics simulation technique. We present an atom-resolved analysis method that includes physical quantities such as the root-mean-square bond-length fluctuation and coordination number for individual atoms as functions of temperature. The effect of a central atom in the icosahedral structure to the melting process is discussed. The results show that the global minimum structures of the 54-, 55- and 56-atom Pt clusters do not melt at a specific temperature, rather, melting processes take place over a finite temperature range. The heat capacity peaks are not delta-functions, but instead remain finite. An ensemble of clusters in the melting region is a mixture of solid-like and liquid-like clusters.

    Fragmentation of a Non-Rotating Ni19 Cluster: A Molecular Dynamics Study
    (1999) Güvenç, Ziya Burhanettin; Çivi, Mehmet; Güvenç, Ziya Burhanettin; Jellinek, Julius; Bilgisayar Mühendisliği
    Collisionless fragmentation of a non-rotating Ni19 cluster is studied using constant-energy molecular dynamics computer simulations. The cluster is modelled by an embedded atom model (EAM) energy surface. Distribution of the channel-specific fragmentation probabilities, and global rate constants are computed and analyzed as functions of the internal energy of the cluster. The results are compared with those obtained using the RRK statistical approach, and also compared with the other multi-channel fragmentation work.

    D2 +Nin(T), n=7 and 9, Collision System
    (1999) Güvenç, Ziya Burhanettin; Durmuş, Perihan; Özçelik, Süleyman; Güvenç, Ziya Burhanettin; Jellinek, Julius; Bilgisayar Mühendisliği
    In this study the kinetics of reactions of Nin n=7 and 9, clusters with a deuterium D2 molecule are studied via quasiclassical molecular dynamics. Dissociative chemisorption probabilities as functions of impact parameters, collision energies, and a rovibrational state of a molecule are calculated. And the corresponding reactive cross sections are evaluated. Resonance formation in the low collision energy region is discussed.
