  The suitability of a range of interatomic potentials for elemental tin was
evaluated in order to identify an appropriate potential for modeling the
stanene (2D tin) allotropes. Structural and mechanical properties of the flat
(F), low-buckled (LB), high-buckled (HB), full dumbbell (FD), trigonal dumbbell
(TD), honeycomb dumbbell (HD) and large honeycomb dumbbell (LHD) monolayer tin
(stanene) phases, were gained by means of the density functional theory (DFT)
and molecular statics (MS) calculations with ten different Tersoff, modified
embedded atom method (MEAM) and machine-learning-based (ML-IAP) interatomic
potentials. A systematic quantitative comparison and discussion of the results
are reported.
