ELECTRON TRANSPORT IN TA2O5 NANOLAYERS WITH CONDUCTING POLYMER CATHODE
Original language description
The paper will present the modeling of charge transport in Ta2O5 nanolayers together with experimental verification of the model. MIS structure model for tantalum capacitors with conducting polymer cathode will be described on the base of the leakage current analysis. Ta205 films show good electrical and dielectric properties for considered applications and low leakage current density value 10-4A/m2 for the electric field 100 MV/m. Dominant mechanism of charge carrier transport is ohmic conduction for the low electric field, while Poole-Frenkel mechanism becomes dominant for electric fields in the range 100 to 200 MV/m. Tunneling current becomes dominant for the electric field higher than 200 MV/m. Ohmic current component and Poole-Frenkel current component are thermally activated, while the tunnelling current component is temperature independent. We have observed that for temperatures above 250 K the leakage current is given predominantly by the ohmic and Poole-Frenkel mechanism. For
