Lanthanum-modified lead titanate thin film capacitors: Processing, microstructure, and properties

Polycrystalline paraelectric (Pb;The leakage current (;Specific top-contact metals from two distinct groups were selected to understand the electrical nature of the interfaces in terms of electrode dependent energy band diagrams and equivalent circuit models. Using a high sensitivity high-pass filter circuit to evaluate the charging and discharging behavior coupled with results of the thickness and voltage dependence of capacitance, it was determined that...
