Sequential Electronic and Structural Transitions in VO₂ Observed Using X‐ray Absorption Spectromicroscopy

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.
