Filmkamera für die Nanowelt
Für Momentaufnahmen im Nanometer-Bereich gibt es das Elektronenmikroskop. Doch was kontinuierlich in den winzigen Nanostrukturen abläuft, konnte bisher niemand exakt dokumentieren. Doch nun hat der Lausanner ETH-Spin-off Attolight die Filmkamera für die Nanowelt erfunden. Jetzt kann zum Beispiel gezeigt werden, wie sich Elektronen innerhalb von Laserdioden oder LEDs bewegen oder was für Prozesse in Solarzellen ablaufen.

With Attolight, Cathodoluminescence (CL) is now available in a streamlined system which integrates CL with both light (LM) and electron microscopy (EM): what was a challenging experiment in the past, often done on klunky, home-made devices can now be done easily and efficiently.
Attolight is now changing the landscape: its innovative approach brings nanometer resolution as well as pico-second timing for time-resolved studies, regardless of the wavelengths used.
While any material that emits light under electron irradiation can be studied by CL, it is particularly valuable in material studies of semi-conductor materials, phosphor, ceramic, rock and glass. Combining LM, EM with hyperspectral imaging, Attolight’s solution reveals ultra-trace impurities and crystallographic defects not visible using other imaging modalities. |
