SOLITON CONDUCTIVITY IN HYDROGEN-BONDED FERROELECTRICS
摘要
Abstract
A.Gordon first studied solitonic coductivity in some hydrogen-bonded ferroelectric materials,using the hydrogen bonded chain model with asymmetric double-well potential,and gave the kink solution and expression for its mobility.However,kink solitons making contribution to proton-solitonic conductivity should be the solitons corresponding to proton transfer between two wells.For this reason,we suggest revising Gordon's result,giving a low-energy-state kink solution and a new expression for its mobility.With the asymmertic double-well potential transforming to the symmetric one,this expression is reduced exactly to the same form as previous research result.This expression shows that the phase-transision critical index is 1.关键词
