Ferroelectricity is expected to be observed in alkaline earth metal oxides (BaO, MgO, CaO, and SrO) with the application of adequate strain, according to theoretical predictions by Bousquet et al. The resultant polarization, dielectric constant, and

In this research we correlate the structural parameters obtained from molecular dynamics (MD) simulations and Raman scattering to construct a self-consistent picture of the glass structure, and its variation from ambient temperature to the supercoole

Structural and electronic changes induced by laser irradiation are currently of interest owing to the possibility to tune the mechanical, optical, and transport properties of the irradiated materials. In this work, we investigate the effects of laser

A recent theoretical work by Bousquet and collaborators have predicted that ferroelectric ordering could be induced in the rocksalt oxides of alkaline earth metals (BaO, MgO, CaO and SrO) by strain. The expected functional properties present in these

Described herein is a new approach to produce glass materials using a CO2 laser as unique heating source. In this study, the well-known PbO·SiO2 (PS) system was chosen as a glass model because of its very good glass forming ability and stoichiometri

The rocksalt (B1) to CsCl (B2) pressure-induced structural transformation in CaO is investigated with isenthalpic-isobaric molecular dynamics simulations. The analysis of the dynamic transformation reveals an atomic mechanism following a pathway form

The temperature- and pressure-induced structural phase transition in PbTiO3 is studied with the isoenthalpic–isobaric molecular-dynamics method, using an effective two-body interaction potential. The tetragonal to cubic transformation is successful
