"The paper presents the experimental analysis of low frequency noise and charge carrier transport mechanisms in Nb2O5 thin films. The ohmic conduction is dominant for the low electric field. Poole-Frenkel and Schottky mechanism become dominant for electric fields up to 125MV/m. Tunneling current becomes dominant for electric field higher than 125-175 MV/m. This value depend on the temperature. It was proved experimentally at the room temperature that GR noise is dominant for the low electric field (Poole-Frenkel current and Schottky current), while for the high electric field, where the tunneling current is dominant, the low frequency noise is 1/f type. We have arranged the measuring set-up which allows the CV and IV characteristics and low frequency noise measurements in the temperature range 10 to 400 K. The voltage noise spectral density is 1/f type as we expect for high electric field on the sample. The leakage current is exhibiting the tunneling current component only in the temperature range bell" . "[1485AECF1EE6]" . "Proc. IMAPS CS Int. Conf. Electronic Devices and Systems EDS 2011" .
