“…These glasses are known to be mixed ionic‐electronic conductors . It was found that alkali‐free oxide glasses in the TeO 2 –V 2 O 5 –MoO 3 and V 2 O 5 –Sb–TeO 2 systems have nonohmic conduction leading to negative resistance/switching phenomenon at high electric fields. Binary glasses based on TMO have pure electronic conductivity with a small polaron mechanism of conductivity .…”

Summary The ac conductivity of 70WO3–30P2O5 glass composition prepared by melt quenching was first studied in the temperature range 25°C to 350°C. The conductivity of the semiconducting glass is investigated with various electrodes (Pt and Ga‐Ag alloy). It is shown that the type of spectrum of cell impedance depends on the chosen electrodes. The influence of the samples geometry on the conduction is established. The influence of gas atmosphere (argon, oxygen, and air of different humidity) on electrical conductivity of tungsten‐phosphate glass on is studied for the first time. A mixed electronic‐ionic conductivity in the 70WO3–30P2O5 glass is found out. The transport numbers are shown as a function of temperature. Ionic and electronic contribution to the conduction is estimated. The electrical conductivity of glass undergoes changes from 8.6 × 10−8 (25°C) to 3.1 × 10−4 S/cm (300°C) in air.

Compared with Sb film, V2O5/Sb superlattice-like thin film has better thermal stability (T c ∼ 240 °C, T 10-year ∼ 172.9 °C). V2O5/Sb thin film is suppressed by the multiple interfaces and the grains become smaller. The vibrational peaks of Sb-Sb and V–O bonds are observed by Raman measurement. The interaction between the two crystal systems improves the stability of the V2O5/Sb membrane. The multilayer structures before and after crystallization were observed by transmission electron microscopy. The ultralow-power (2.25 × 10−12 J) and ultrafast-speed (8 ns) has been achieved for V2O5(1 nm)/Sb(9 nm)-based phase change memory device.
