Thermal stability of interface dipole modulation in atomic layer-deposited HfO2/SiO2 multi-stack structures

In this paper, we report on an interface dipole modulation (IDM) loss occurring in HfO2/atomically thin TiO2/SiO2 stack structures prepared by atomic layer deposition (ALD). The IDM characteristic, which is observed as a capacitance–voltage (C–V) hysteresis curve, disappears when the temperature dur...
