Popis:	The electrical switching behaviour of As45Te55-x In-x (5 less than or equal to x less than or equal to 15) and As50Te50-xInx (2.5 less than or equal to x less than or equal to 11.5) has been studied over a wide range of compositions. These glasses are found to exhibit threshold switching. The composition dependence of switching voltage (V-t) has been found to exhibit a change in slope and a local minimum at compositions x = 10 and 12.5 for As45Te55-xInx and x = 7.5 and 10.8 for As50Te50-xInx, respectively. The slope change in V-t verses x and the local minimum have been identified using two network topological effects, namely the rigidity percolation threshold and the chemical threshold.
