Charge Carrier Transport Behavior and Dielectric Properties of BaF:Tb Nanocrystals.

Article Synopsis
- The study investigates the charge carrier behavior and dielectric properties of BaF:Tb nanocrystals using AC impedance spectroscopy, revealing that both electrons and ions participate in conduction.
- As the Tb doping concentration increases up to 4%, the contribution of F ions to conduction rises, boosting ion diffusion and reducing resistance; however, beyond 4%, the increased scattering effects raise resistance and lower diffusion.
- The results suggest that Tb doping enhances carrier hopping probabilities, thereby increasing the permittivity of BaF nanocrystals at low frequencies compared to previous studies on rare-earth-doped BaF single crystals.
