Postcards of the CRC1242
Want to send greeting cards? Then you should check out the cards from our SFB. Anyone who can generate femtosecond laser pulses can also send especially fast (and educational!) postcards. Feel free to download the results from our SFB in postcard format and send them out!!

Electric-field vectors (arrows) of a surface plasmon polariton reveal a skyrmion bag: seven individual skyrmions occupy the central region, while an antiskyrmion surrounds them, forming the bag. The background colormap shows the skyrmion charge-density distribution.

Gold (111) surface, imaged using our low-energy electron microscope. The gold surface featured small “hills” that, in false-color rendering, resemble tiny spring flowers.

Colorized STEM image depicting a micropore covered by MoS2 layers transitioning from single-layered (blue) to multi-layered (red) material. Pores created through ion irradiation can be seen as black dots within the single and double layered regions.

2D materials can not only be exfoliated from bulk material but can also be grown using chemical vapor deposition. However, this requires extremely high temperatures of ≥ 700°C. Here, the tube furnace is shown at its maximum temperature.

The image shows a view inside an ultra-high-vacuum chamber where research is being conducted on so-called 2D materials. These materials consist of only one or a few atomic layers and are among the thinnest known solids. In the center of the image is a sample of graphene—a single layer of carbon atoms—on a silicon substrate at 600 °C. Due to this high temperature, the sample holder visibly glows red.
