  • Abstract
    The conduction and trapping phenomena in very thin (100 Å) thermally grown films of SiO2have been studied and their dependences on temperature have been determined from room temperature to 200 °C. The results of constant current injection trapping studies indicated that the total breakdown charge density decreases approximately linearly with the logarithm of injection current density, J . The total breakdown charge density showed an Arrhenius behavior with temperature and a single activation energy of 0.155 eV was obtained for J = 0.278 A/cm2. The mean breakdown voltage obtained from time dependent electrical breakdown experiments was independent of temperature for a constant J . However, at room temperature the mean breakdown voltage showed a tendency to increase with increasing J .
