Insight on the weak hopping conduction produced by titanium ions in the lead borate glassy system

M. G. Moustafa et al.

Summary: The DC conductivity investigation of lead borate glass system revealed that the addition of TiO2 slightly increased the conductivity of the glasses. The interaction between Pb-ions and Ti-ions led to the weak hopping process in the glasses, with PbO playing a vital role in highlighting this phenomenon without the need for low-temperature measurements.
