Specifically, it examines key parameters like capacitance density (C0=9.3 nF/mm², κ=23.9) and field linearity (α=565 ppm/(MV/cm)²). It also assesses lifetime characteristics (tBD|150°C=3.6∙1010 s), while shedding light on the dominant conduction mechanism.enDielectricsMIM capacitorsCapacitorsconference paper
