Melting of 2D glassy monatomic systems is studied via molecular dynamics (MD) simulations. 2D glassy models are obtained by cooling from the melt and then are heated with Lennard–Jones–Gauss (LJG) interaction potential. Temperature dependence of various structural and dynamical properties of the systems during heating is analyzed and discussed via partial radial distribution functions (PRDFs), coordination number distributions, ring statistics, mobility of atoms and their clustering. We found a transition temperature region, in that structural and dynamical properties of systems strongly change. In addition, we also found that fraction of atoms with very low mobility (solidlike ones) decreases with increasing temperature down to zero. This research is funded by Vietnam National University - Ho Chi Minh City (VNU-HCM) under grant number B2017-20- 02.
