Model for the semiconducting uniaxial ferroelectric Fe1-xS—Part I

摘要: This is part I of a series papers in which qualitative model for semiconducting uniaxial ferroelectric developed terms Fe1-xS was recently shown to be such ferroelectric.Two types charged defects are responsible the anomalous behaviour, since they both weaken polar coupling: (i) electronic belonging lattice (e defects) and (ii) vacancy-connected (v defects). The transition from 2c phase paraelectric lc proceeds via sequence transitions can typified following scheme[image omitted] A TPS (Two Phase Structure) double junction rectifiers alternate polarity that spontaneously form: positive (negative) segregate into space-charge layers having increased defect density paraelectric. space charge cancels depolarizing field connected with terminal charges decreased polar.It ...
