Abstract:

 

Electrical switching behaviour of lead phosphovanadate  glasses were studied by determining the current-voltage  characteristics.  All the investigated glasses exhibit the dependence  of threshold voltages on temperature, thickness and composition.   Below holding current the I - V characteristics obey Ohms law followed  by a negative resistance region where the bulk behaviour dominates and  at higher values of current the samples goes to a low resistance  state.  The studied glasses exhibit memory type switching.  It is  suggested that the initial switching and channel formation are due to  electronic, while thermal effects dominate in the formation of  channels.
