在这项工作中，一个高度无序的非晶VO 2薄膜的相变进行了研究。结果表明，薄膜的电子输运行为符合Arcidius或Vogel-Tammann-Fulcher模型，在不同厚度下表现出不同的热敏性。在此基础上，论证了具有过热保护功能的原型装置的概念。这些结果反映了相变和结构无序之间的关系，为理解强关联电子系统中的金属绝缘体转变及其在电子器件中的功能开辟了一条独特的途径。
In this work, the phase transition of a highly disordered amorphous VO2 film is studied. It is found that the electronic transport behavior follows the Arrhenius or Vogel–Tammann–Fulcher model, showing different thermal sensitivity under different thicknesses. Based on it, the concept of a prototype device with overheating protection capability is demonstrated. The results, reflecting the relationship between phase transition and structural disorder, open up a unique pathway to understand the metal insulator transition in strongly correlated electronic systems and to its functionality in electronic devices.
