钒氧化物薄膜($VO_{2}$)结构相变电阻的均匀温度依赖性的观测

Observation of a uniform temperature dependence in the electrical resistance across the structural phase transition in thin film vanadium oxide ($VO_{2}$)

R. G. Mani, S. Ramanathan

摘要:

在$68^{0}C$处的结构相变附近的$VO_{2}$薄膜的电学研究表明(a)在$T$范围内,电阻$R$遵循$log (R)$ $\propto$ $-T$,$20 < T < 80 ^{0}C$覆盖结构转变的两侧,以及(b)热循环时$R$中的历史依赖性磁滞回线。这些特征在这里归因于通过颗粒网络的传输。

英文摘要:

An electrical study of thin $VO_{2}$ films in the vicinity of the structural phase transition at $68^{0}C$ shows (a) that the electrical resistance $R$ follows $log (R)$ $\propto$ $-T$ over the $T$-range, $20 < T < 80 ^{0}C$ covering both sides of the structural transition, and (b) a history dependent hysteresis loop in $R$ upon thermal cycling. These features are attributed here to transport through a granular network.
