Abstract
In this study, we have fabricated metal-insulator-metal (MIM) capacitors where the insulator layer is made of 255¿nm diameter silica nanospheres. The MIM devices have been characterized and modeled by electrochemical impedance spectroscopy (EIS) and charge-discharge transients. Fitting the results with modified Randles models agreed well with three constant phase elements, three leakage resistors, and a Warburg element. According to the results of the fitting of the charge-discharge measurement...
