Investigations on dynamic characteristics of ferroelectric Hf02 based on multi-domain interaction model
We have investigated dynamic characteristics of ferroelectric Hf02 (FE-HfÓ2) by considering multiple domain (MD) and linear domain-domain interaction. By using the calibrated MD model, experimental dynamic responses of FE-HfO2 can precisely reproduced, for the first time. Input voltage amplitude (Vin) and external resistance (R) dependences of dynamic responses in FE-HfO2 revealed that dynamic term (ρi) of Landau-Khalatnikov equation in MD FE-HfO2 is not constant but depends on Vin due to domain dynamics.
