Compositional Analysis
Energy Filtered TEM

These images were collected using the Gatan Image Filter on the JEOL 2010F TEM/STEM from a BN sample dispersed on a holey carbon film. The electron energy loss spectrum shows families of peaks for B, C, and N in order of increasing energy loss (upper left). The images at the upper right and lower left are EFTEM maps for B and C, respectively. The image on the lower right represents a combined map for B (blue) and C (yellow).
