Achieving a high dielectric tunability in strain-engineered tetragonal K0.5Na0.5NbO3 films
Abstract Using a modified Landau-Devonshire type thermodynamic potential, we show that dielectric tunability η of a tetragonal ferroelectric film can be analytically solved. At a given electric field E, η is a function of the remnant polarization ( $$P_0^f$$ P 0 f ) and the small-field relative diel...
