ESCHER, Susanne G.E.T.; DUNCAN, Helen D.; SOKOL, Alexey A.  and  WOODLEY, Scott M.. Approaching Bulk from the Nanoscale: Extrapolation of Binding Energy from Rock-Salt Cuts of Alkaline Earth Metal Oxides. S.Afr.j.chem. (Online) [online]. 2021, vol.74, pp.23-29. ISSN 1996-840X.  http://dx.doi.org/10.17159/0379-4350/2021/v74a5.

A systematic DFT study is performed on (MgO)_B, (CaO)_n, (SrO)_n, and (BaO)_n clusters with 6 < n < 50, and which display a cuboid 2X2X2 atomic motif seen in the bulk, rock-salt, configuration. The stability and energy progression of these clusters are used to predict the energies of infinitely long nanorods, or nanowires, slabs, and the bulk global minimum energy.

Keywords : Alkaline earth metal oxides; nanoclusters; nanorods; DFT.
