Exploring the Interrelation between Urbach Energy and Dielectric Constant in Hf-Substituted BaTiO(3)
[Image: see text] The variation of dielectric constant (ε(r)) in the low-frequency region (∼10(6) Hz) in Hf-substituted BaTiO(3) has been modelled considering the electronic disorder in the form of Urbach energy (E(U)) with the help of a Bohr-like model. Optical absorption spectroscopy has been empl...
