摘要
The on-off fluctuations of the tunnel current in 5.6 nm SiO2 films before dielectric breakdown are analyzed in detail. For this purpose, a low noise measurement system has been realized which allows detecting the pre-breakdown phenomena and interrupting the stress before the catastrophic failure occurs. A spectral analysis of these fluctuations is presented along with the preliminary results of the experiments made possible, for the first time, by the new measurement system.
