Abstract :
This paper deals with the capacitance response of metal-insulator-metal (MIM) structures with 15 nm thick Al2O3 as dielectric. Electrical characterizations between 100 K and 450 K have been performed to study the temperature effect on the capacitance. An original model assuming that the permanent moment of the polar molecules in the Al2O3 film grows linearly with temperature is exposed to explain the experimental results.
