Webb15 sep. 2024 · The notion of antiferroelectrics (AFEs) can go back to 1950s, Kittle et al. put forward a thermodynamic model based on Landau theory to study the phase transition of AFEs, where two sub-lattices with different polarization were used to separate antiferroelectric (AFE) state from ferroelectric (FE) state [1 ].
WebbAntiferroelectric liquid crystals (AFLCs) are a type of liquid crystals (SmC*A ) [6-10] in which spontaneous polarization has been created on different layers due to the helical superstructure. The c-director of the adjacent layers of AFLCs is nearly antiparallel to each other because of its anticlinic nature. list of buckinghamshire railway stationsWebbför 15 timmar sedan · With the new prequel series Crystal Lake creeping onto Peacock TV, it has the opportunity to address one of Friday the 13th's strangest sequels.
