The calculations are performed within the time-dependent density functional theory, including local field effects. The theoretical calculations show that the perovskites have a plasmon mode at around 12 eV, which is not observed in experiments.</p>}, number={1}, journal={Communications in Physics}, author={Phuc, Le Hong and Hien, Nguyen Quang and Nguyen-Truong, Hieu T. and Le, Hung M.}, year={2022}, month={Jan.}, pages={49} }
