Ultra-violet to visible band gap engineering of cubic halide KCaCl 3 perovskite under pressure for optoelectronic applications: insights from DFT

in microelectronics, integrated circuits, QLED, OLED, solar cells, waveguides, solar heat reduction materials, and surgical instruments has been suggested through deep optical analysis. The use of external hydrostatic pressure has a considerable impact on the mechanical properties of this material, making it more ductile and anisotropic.
