During the next few years, considerable growth of industrial, commercial, and residential loads is anticipated in northeastern Afghanistan. Already, Afghanistan imports 900 megawatts of power from Uzbekistan, Tajikistan, and Turkmenistan. The capacitor banks at Chimtala and the north substation in Kabul are in operation.
We report on a measurement procedure to separate ferroelectric switching current and dielectric displacement current from the leakage current in leaky ferroelectric thin-film capacitor structures. The ac current response is determined for two adjacent frequencies. Taking advantage of the different frequency dependencies of the ferroelectric switching current, …
