| Abstract: | The synthetic fused quartz glasses with bare metal impurities have been analyzed by temperature-dependent electrical impedance spectroscopy. The complex electric impedance and the overlapping of the normalized dielectric modulus imply the single mechanism of dielectric and conduction relaxation in the fused quartz glass. Besides, the dependence of conductivity on temperature may attribute to the predominant electric relaxation to the delocalized or long range electronic hopping between the nonbridged dangling oxygen. |
