Two-dimensional materials such as graphene, transition metal dichalcogenides (TMDs) or hexagonal boron nitride (hBN) are among the most fascinating areas of modern science. Thanks to their unique electrical, optical and mechanical properties, they open the door to new technologies in quantum computing, optoelectronics and energy storage. However, to fully exploit their potential, accurate analytical methods are crucial.
This is where the SNOM microscope cryo-neaSCOPE+XS comes in: a tool that delivers nanometer-scale imaging across a broad spectral range from the visible to the infrared to terahertz. Its cryogenic measurement solution enables the study of materials at temperatures down to 4 K, which is essential for investigating quantum phenomena, superconductivity, and phase transitions. Advanced spectroscopic capabilities enable hyperspectral imaging and detailed analysis of local optical responses – all contributing to a deeper understanding of plasmonic and excitonic phenomena in 2D semiconductors.
The Attocube 2D Materials Conference 2024 brought a number of inspiring presentations, which you can now watch:
Imaging optical quasiparticles in 2D materials
William Wilson (Harvard University, USA) presented advanced research in nanoscience and quantum technologies. Using scan-probe techniques, he visualized complex phenomena such as polaritons and correlated electron systems, and showed innovative applications of these methods in interdisciplinary research.
