Structure and Lattice Dynamics of Calcium Chalcogenides under High Pressure
Structure and Lattice Dynamics of Calcium Chalcogenides under High Pressure is a scholarly work, published in 2018 in ''Materials Today : proceedings''. The main subjects of the publication include calcium, dynamics, lattice, Solid acid fuel cell, phase-change memory, materials science, chemical physics, statistical physics, and condensed matter physics. The authors have also calculated the phonon dispersions of these three compounds in B1 phase and are found to be dynamically stable even after the phase transition pressure to maximum pressure of the present study (50 GPa) for CaS, CaSe whereas CaTe is stable up to 30 GPa.
