AC conductivity of binary silver phosphate glasses


Chow, Sai Pew and Shaari, Abdul Halim and Leong, M. L. and Yow, H. K. and Abd. Aziz, Sidek and Hassan, Senin (1998) AC conductivity of binary silver phosphate glasses. In: 1998 IEEE International Conference on Semiconductor Electronics (lCSE'98), 24-26 Nov. 1998, Equatorial Hotel, Bangi. (pp. 47-53).


Samples of binary silver phosphate glasses with composition (Ag2O)x(P2O5)1-x have been prepared and their ac electrical conductivities measured over a range of frequency, composition and temperature. It is observed that a.c. conductivity increases very gradually at low frequency (below 1 kHz), but rapidly at higher frequency (above 10 kHz). Conductivity as high as 10-5 Scm-1 has been observed depending on the composition, frequency and temperature of the samples. It increases almost linearly with the mole fraction of Ag2O. As a function of temperature, the conductivity increases too with temperature. Arrhenius plot is obeyed and activation energy of 0.41 to 0.46 eV has been obtained.
