Low-Dose and High-Speed In-Situ TEM with the K3 IS Camera

The versatile K3 IS direct detection camera is allowing for in-situ characterization of material reactions with high ease-of-use and unhindered switching between low-dose and high-speed imaging. The large field of view with the K3 IS camera has enabled investigations on nanoparticle transformations and dynamics at a temperature within the environmental TEM, lithiation of battery anodes, and 4D STEM strain mapping of nanowires post in-situ testing. Additionally, the low-dose functionality has been paired with cryogenic imaging of beam-sensitive materials including battery electrodes/electrolytes and metal-organic frameworks. Beam-sensitive environmental imaging takes advantage of this advanced camera for real-time frame averaged viewing prior to the collection of stimulated events in the sample, where the look-back feature prevents crucial images from being lost.

This webinar will highlight the functionality of the K3 IS camera for in-situ and low-dose imaging of an array of reactions and materials, to showcase its versatility and user-friendly capabilities. Our work specializes in in-situ studies, where fast reactions and beam-sensitive materials will be covered in the most detail.
