Abstract :
Capacitance, dielectric permittivity and losses are presented as a function of temperature, frequency, DC voltage, insulator thickness, and electrode material for Dy2O3 and Yb2O 3 thin films deposited in MIM (metal-insulator-metal) sandwiches. Results show that both volumes of the dielectric films as well as the M/I interfaces (Schottky barriers) are responsible for the dielectric response of these capacitors
