Influence of lithium phosphate concentration and temperature on the electrical conduction of (76V2O5–24P2O5)1−X (Li3PO4)X glasses Original Research Article

Characterization of the (76V2O5–24P2O5)1−X (Li3PO5)X, where X=0.0,0.01,0.02,0.10 and 0.15, glass has been done using X-ray diffraction and differential thermal analysis (DTA). The dc conductivity of the glass samples was studied over a temperature range from 300 to 593 K. The temperature dependence of dc conductivity shows two regions. One at relatively high temperature range, above θD/2, and the other at relatively low temperature range, below θD/2. The I–V characteristics of the glasses have been studied as a function of both temperature and Li3PO4 content. The I–V characteristics exhibits threshold switching with differential negative resistance. Itʹs found that both the threshold voltage (Vth) and threshold current (Ith) are dependent on the temperature and lithium phosphate concentration.
