柔性电子产品有很大的潜力影响消费电子产品，并与我们的日常生活。目前，在市售的柔性衬底上直接生长外延功能氧化物是不可能的。在这项研究中，为了解决这一挑战，白云母，一种常见的层状氧化物，被用作一个灵活的基板，是化学上类似于典型的功能氧化物。采用脉冲激光沉积技术在白云母上制备了MoO2外延薄膜。X射线衍射和透射电子显微镜的组合证实了异质结构的货车范德华外延。MoO_2薄膜的电输运性质与体材料相似。可以获得柔性或独立的MoO2薄膜，并作为模板来集成额外的功能氧化物层。我们的研究展示了一个基于功能氧化物制造柔性电子产品的非凡概念。
Flexible electronics have a great potential to impact consumer electronics and with that our daily life. Currently, no direct growth of epitaxial functional oxides on commercially available flexible substrates is possible. In this study, in order to address this challenge, muscovite, a common layered oxide, is used as a flexible substrate that is chemically similar to typical functional oxides. We fabricated epitaxial MoO2 films on muscovite via pulsed laser deposition technique. A combination of X-ray diffraction and transmission electron microscopy confirms van der Waals epitaxy of the heterostructures. The electrical transport properties of MoO2 films are similar to those of the bulk. Flexible or free-standing MoO2 thin film can be obtained and serve as a template to integrate additional functional oxide layers. Our study demonstrates a remarkable concept to create flexible electronics based on functional oxides.
