Ultrafast laser light can create emergent polar orders in specially designed thin-film heterostructures. A single-shot X-ray diffraction study, over a timescale of seven orders of magnitude, has revealed how one such polar supercrystal forms with lattice periodicities of tens of nanometres.

追踪不可逆的光诱导从无序中产生扩展的极序


超快激光可以在专门设计的薄膜异质结构中产生紧急极序。一项在七个数量级的时间尺度上的单发 X 射线衍射研究揭示了这样的极地超晶是如何形成具有数十纳米晶格周期的。
