Ein Röntgenkondensator, aufgenommen unter einem Lichtmikroskop

An X-ray condensing beamshaper, captured under a light microscope. Its intricate geometry diffracts visible light, unveiling a spectrum of radiant colors, where each hue signifies a unique line periodicity. The diameter of the beamshaper is 2 mm, and the thinnest linewidth is 50 nm. The device was developed for the X-ray microscope operated by the Hereon Research Center, Germany.

Electron Backscatter Diffraction color crystal orientation map of a 3D-printed (additively manufactured) stainless steel, after etching the surface to reveal the melt pool tracks. The material is porous (pores seen as black dots at the tips of the meld pool tracks) which interrupts the epitaxial growth of the crystallites in the material during solidification. Therefore every melt pool consists of several small crystallites with different orientation.

Nano Image Award 2020

Gate Array Rasterelektronenmikroskopische Aufnahme von Teilen einer Spin-Qubit-Vorrichtung, die durch Elektronenstrahl-Litho- graphie hergestellt wurde. Sie ist in Regenbogenfarben eingefärbt, weil sich die Strukturen in einem Abstand, der etwas kleiner als die Wellenlänge des sichtbaren Lichts ist, anordnen und sich daher je nach Betrachtungswinkel in unterschiedlichen Farben zeigen.

Gulibusitan Abulizi: A real-color optical microscope image of an hexagonal boron nitride flake on a silicon oxide substrate The observed optical colors are due to interference effect, which can be used to determine the hexagonal boron nitride (hBN) flake thickness. Here, the observed color progresses from violet to blue, to green, to yellow, to orange, and to red, while the hBN flake thickness increases.
