ABSTRACT
Based upon a defined surface barrier in ferroelectric multilayers deposited on (100) p-type silicon, ξV[sub a], which bears a portion of the external electrical voltage, a modified empirical power law I =A(ξV)[sup n] is established for quantitatively describing detailed I-V dependence in ferroelectric multilayers. The voltage drop at the interface, V[sub i], which directly affects electrical characteristics of ferroelectric multiplayer system, is studied thoroughly. The voltage drop obtained from the modified empirical power law of the I-V dependence is consistent with that obtained from the C-V dependence model.
