论文摘要
薄膜vo $ _2 $的生长和表征的最新进展表明,通过外延匹配可以显着调节其电子特性。为了对“ Mott Engineering”的概念进行新的启示,我们开发了一种对称性的方法来治疗在劳累下的外延vo $ _2 $胶片中的结构扭曲和电子相关性,并将我们的设计与直接的实验探针进行比较。我们发现了有力的证据表明,相关驱动的电荷顺序在金属阶段深处,我们的结果表明,可以通过外延稳定来控制Vo $ _2 $的外来阶段。
Recent progress in growth and characterization of thin-film VO$_2$ has shown its electronic properties can be significantly modulated by epitaxial matching. To throw new light on the concept of `Mott engineering', we develop a symmetry-consistent approach to treat structural distortions and electronic correlations in epitaxial VO$_2$ films under strain, and compare our design with direct experimental probes. We find strong evidence for the emergence of correlation-driven charge order deep in the metallic phase, and our results indicate that exotic phases of VO$_2$ can be controlled with epitaxial stabilization.
