Preparation of +4-Valent Vanadium Oxide Films via the Co-Sputtering of Mg and V₂O₅

Advanced Electronics Materials and Devices, Shanghai Jiao Tong University, Shanghai 200240, China

摘要

摘要: 在常温、高真空条件下，采用高纯金属镁靶和V₂O₅靶进行共溅射，利用镁原子的还原性，将+5价的钒还原为+4价，在硅衬底上制备钒的氧化物薄膜。当Mg和V的原子比为1:2时，XPS测试表明薄膜中有V⁴⁺和V²⁺存在。X射线衍射结果显示，制备的薄膜主要成分是MgV₂O₅，且结晶状况良好。温度-电阻率测试结果显示，薄膜在20℃附近有相变行为，电阻温度系数高达－8.6%/K，回线弛豫温度约为0.3℃，负温度系数热敏电阻材料常数高达6700。这一发现为制备非制冷焦平面探测用的热敏薄膜材料提供了新的思路。

Abstract: Vanadium oxide films were deposited on a silicon substrate via co-sputtering a high-purity magnesium and vanadium pentoxide target under high vacuum at room temperature. Owing to the reducibility of the magnesium atom, the valency of vanadium was reduced from +5 to +4. When the atomic ratio of Mg to V was 1:2, X-ray diffraction (XRD) results showed that the main component in the film was MgV₂O₅. X-ray photoelectron spectroscopy (XPS) results showed that both V⁴⁺ and V²⁺ were present in the fabricated films. The crystallization of the MgV₂O₅ film was in adequate condition, as observed in the SEM profiles. The results of the temperature resistivity test showed that the film experienced a phase transition near room temperature. The hysteresis loop occurred at a temperature of approximately 0.3℃ with a temperature coefficient of resistance of −8.6%/K. The material constant of the negative temperature coefficient thermistor was approximately 6700. This discovery provides a novel method for the preparation of thermal film materials for application in uncooled focal plane detectors.
