TLDR
A bridge is built between the hysteretic behavior observed either in the C- E and current-electric field characteristics on a MFS structure and the current characteristics of the BCZT/ZnO bilayers in a metal-ferroelectric-semiconductor (MFS) configuration.Abstract:
In the present work, we study the hysteretic behavior in the electric-field-dependent capacitance and the current characteristics of 0.5Ba(Zr0.2Ti0.8)O3–0.5(Ba0.7Ca0.3)TiO3 (BCZT)/ZnO bilayers depo...read more
