“…The glasses are highly conductive compared with V 2 O 5 -P 2 O 5 glasses and other glasses containing transition-metal oxides with the same amounts of charge carriers [2][3][4]. In the V 2 O 5 -TeO 2 glasses both memory and threshold switching functions have been also reported [5][6][7].…”

The structures of V2 O5 -TeO2 glasses are investigated by means of 125 Te and 51 V static NMR spectroscopies and the local structures around the Te and V atoms are discussed in detail from the respective NMR spectra. The fraction of TeO3 trigonal pyramids increases and that of TeO4 trigonal bipyramids decreases with increasing V2 O5 content. The structures of V2 O5 -TeO2 glasses are quite different from those of tellurite glasses containing network-modifying oxides. The fraction of VO4 tetrahedra increases and that of VO5 trigonal bipyramids decreases with increasing V2 O5 content. Both chains consisting of tellurite structural units and those consisting of vanadate structural units contribute to the formation of the glass network in V2 O5 -TeO2 glasses.

“…Such glasses are well known to be semiconductors with relatively high conductivity and they possess memory and threshold switching functions [2][3][4]. Therefore a lot of studies have been devoted to the analysis of V 2 O 5 effects on both the structure and properties of these glasses [5][6][7][8].…”

“…4); i.e., the material does not get latched on to the highconducting state permanently. The glasses (x ‫ס‬ 15,20) show an initial ohmic response (region A) and at V t change course to a stable negative resistance state (region B), which is also characterized by high-rise conductivity. Upon decrease of current values the I-V trajectory C follows closely region B with slight hysteresis to ultimately revert to region A which is the OFF state.…”

Effect of CuO addition on the high-field and high-pressure behavior of microwave-prepared lead vanadate glasses

High-field and high-pressure behavior of microwave-prepared xCuO:(45−x) PbO: 55V 2 O 5 (x ‫ס‬ 0 to 20) glasses were investigated for the first time. It was found that the addition of CuO significantly alters the nonlinear I-V characteristics of these glasses; while the glasses with x ‫ס‬ 10 exhibit a current-controlled negative resistance behavior associated with a memory type transition, glasses with x ‫ס‬ 15 show a threshold-type behavior. Remarkable differences were also noticed in the high-pressure electrical resistivity behavior between the low-and high-CuO-containing glasses. Corroborative thermal, electrical, microscopic, and spectroscopic measurements were carried out to understand the structure-property relations. A structural model was proposed, which is based on the chemical nature of the constituents present in the glasses. The model accounts well for the various observed properties of these glasses.
