Abstract: | 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. It's found that both the threshold voltage (Vth) and threshold current (Ith) are dependent on the temperature and lithium phosphate concentration. |
