This work reports a large controllability of domain evolution in BaTiO3 ferroelectric nanodot by isotropic surface charge screening (SCS). The phase field simulations show that the nanodot can exhibit fruitful domain patterns and evolution paths as functions of temperature and screening factor and changing direction of these two variables. Four typical types of experimental processes have been simulated,...
In order to demonstrate the control of BiFeO3 thin film on the resistive switching effect and achieve the high-performance resistive switching device, the single layers and bilayer have been fabricated by chemical solution deposition method, respectively. In comparison with the single films, the composite film exhibits great performance of the resistive switching in endurance and repeatability, high...
