Isotope analysis in the transmission electron microscope [PDF]

Nature Communications, 2016
Electron microscopy can reveal a material’s chemical structure down to the atomic level, but has so far been blind to isotopic differences. Here the authors are able to map isotope concentrations in graphene by measuring the probability of ejecting atoms,

Exploring the environmental transmission electron microscope [PDF]

Micron, 2012
The increasing interest and development in the field of in situ techniques have now reached a level where the idea of performing measurements under near realistic conditions has become feasible for transmission electron microscopy (TEM) while maintaining high spatial resolution. In this paper, some of the opportunities that the environmental TEM (ETEM)
