Slawomir Prucnal,Fang Liu,Matthias Voelskow,Lasse Vines,Lars Rebohle,Denny Lang,Yonder Berencén,Stefan Andric,Roman Boettger,Manfred Helm,Manfred Helm,Shengqiang Zhou,Wolfgang Skorupa +12 more
TL;DR: Ion implantation followed by rear side flash-lamp annealing (r-FLA) is used for the fabrication of heavily doped n-type Ge with high mobility, which enables to exploit the plasmonic properties of Ge for sensing in the mid-infrared spectral range.
Journal ArticleDOI

TL;DR: The s-SNIM is a scattering-type scanning near-field infrared microscope based on a non-contact atomic force microscope and thus can be complemented in situ by various other AFM techniques, such as topography profiling, piezo-response force microscopy (PFM), and/or Kelvin-probe force microscopeopy (KPFM).

TL;DR: In this article, a dielectric lamella of subwavelength size in all three spatial dimensions behaves as a compact superlens that operates at infrared wavelengths and can be positioned to image any local microscopic area of interest on the sample.
