New　insights　into　polarization　dynamics　in　hafnium　oxide-based　ferroelectrics　with　cylindrical　shell　structures　are　presented　based　on　a　phase-field　modeling.　By　introducing　in-plane　radial　electric　field,　a　center-type　quadrant　domain　with　charged　domain　wall　can　be　created,　which　are　topologically　protected　owing　to　cylindrical　geometrical　confinement.　More　importantly,　reversible　switching　of　the　four-quad　domain　between　convergent　and　divergent　states　can　be　realized　through　the　domain　nucleation,　growth　and　rotation　processes,　that　are　driven　by　domain　wall　motion,　split　and　merge.　Quantum　transport　calculation　predicts　the　emergence　of　a　domain-wall　tunneling　electro-resistance　effect,　due　to　the　broken　curvature　symmetry　between　inner　and　outer　boundaries.　Furthermore,　ferroelectric-antiferroelectric　(FE-AFE)　phase　transition　occurs　with　reduced　radius　of　cylinder　shell.　These　microscopic　insights　into　connections　between　domain　patterns　and　charge　transports　are　helpful　in　designing　three-dimensional　ferroelectric　devices.　　©　1980-2012　IEEE.
