Dynamics of domain walls in hydrogen-bonded ferroelectrics

Research output: Contribution to journal › Article › peer-review

Abstract

The solitonic mechanism for the protonic transfer is used to calculate a mobility of domain walls in hydrogen-bonded ferroelectrics. A one-dimensional model is considered. It is assumed that the sequence of proton jumps in double-minimum wells of hydrogen bonds brings about a domain wall motion. Calculations carried out for KH₂PO₄ crystals can explain the high mobility of domain walls in these substances.
