Query: Charge Dependence of Temperature-Driven Phase Transitions of Molecular
  Nanoclusters: Molecular Dynamics Simulation   Phase transitions (liquid-solid, solid-solid) triggered by temperature
changes are studied in free nanosized clusters of TeF_6 (SF_6) with different
negative charges assigned to the fluorine atoms. Molecular dynamics simulations
at constant energy show that the charge increase from q_F=0.1 e to q_F=0.25 e
shifts the melting temperature towards higher values and some of the metastable
solid states disappear. The increased repulsive interaction maintains the order
in molecular systems at higher temperatures.
