When Cubic Is Not Isotropic: Phonon-Exciton Decoupling in CuInSnS Single Crystals
Lara Kim Linke, Yvonne Tomm, Xinyun Liu +9
Atomic-scale disorder can create hidden optical anisotropy even in crystals that are structurally cubic on average. Here, we show that CuInSnS single crystals host locally symm…

snompy: a package for modelling scattering-type scanning near-field optical microscopy
Tom Vincent, Xinyun Liu, Daniel Johnson +5
Scattering-type scanning near-field optical microscopy (s-SNOM) is a powerful technique for extreme subwavelength imaging and spectroscopy, with around 20 nm spatial resolution. Bu…
