Abstract
The popular dual electronic and structural transitions in VO2 are explored using X-ray absorption spectromicroscopy with high spatial and spectral resolutions. It is found that during both heating and cooling, the electronic transition always precedes the structural Peierls transition. Between the two transitions, there are intermediate states that are spectrally isolated here.
摘要
利用具有高空间和光谱分辨率的 X 射线吸收光谱显微镜研究了 VO2 中常见的双电子和结构相变。结果发现，在加热和冷却过程中，电子跃迁总是先于结构 Peierls 相变。在这两个相变之间，存在光谱上隔离的中间态。
