Vibrational and optical spectroscopies integrated with environmental transmission electron microscopy



Matthieu C. Picher, Stefano Mazzuccoo, Steven R. Blankenship, Renu Sharma


Here, we present a measurement platform for collecting optical spectroscopy data during high-resolution environmental transmission electron microscopy observations of dynamic processes. Such coupled measurements are made possible by the insertion of a parabolic mirror below the sample holder which can focus a laser on the sample and collect scattered photons. This versatile optical setup combines in situ atomic scale electron microscopy observations of nanoscopic scale processes with Raman and cathodoluminescence spectroscopies data obtained at the same time and from a sample area that includes the area observed by TEM. Moreover, the setup provides a local temperature probe of the TEM sample and the laser can also be used as a local heating source and for other light/matter interactions investigations.
