Abstract
Provided herein are a capacitor, a memory device including the capacitor, and a method of manufacturing the capacitor. The capacitor is manufactured by directly depositing a metal electrode having high ion mobility on an ultrathin ferroelectric layer having a certain thickness, and thus may simultaneously use metal cation migration and ferroelectric polarization inversion, and a low-power and high-performance capacitor capable of being selectively activated may be provided by simultaneously controlling an external electric field and an internal electric field caused by polarization of the inside of a ferroelectric thin film.
