Lattice dynamics and phonon characteristics of complex perovskite microwave ceramics

Lattice dynamics and phonon characteristics of complex perovskite microwave ceramics

Complex perovskite microwave dielectric ceramics (MWDCs) of [inline-formula]-type (A = Ba, Sr,…; B′ = Mg, Zn,…; B″ = Nb, Ta), which exhibit excellent dielectric properties, have currently been widely used in microwave and millimetre wave devices. Vibrational spectra, including both Raman and far-inf...
