Transmission electron microscopy

Transmission electron microscopy is a general type of electron microscopy that generates an image of the internal structure of a thin sample using a beam of electrons to achieve much higher spatial resolution than light microscopy.

    Conventional crystal growth models assume crystals grow into a structure-less liquid, even though liquid metals have shown evidence of structural ordering. Here, the authors show crystal growth can be influenced by the presence of thermodynamically unstable local structural order in the liquid.

    Highly ordered and compositionally complex ceramics are prone to disordering under irradiation, but exactly how is unclear. Here, the authors use high resolution microscopy to directly image the order-to-disorder phase transformations in Ti3AlC2 into otherwise unattainable solid solutions.

    Phase change random access memory relies on phase transformation, from a metastable rock salt structure to a stable hexagonal structure, details of which remain unclear. Here the authors use atomic resolution energy dispersive X-ray spectroscopy to probe the atomic-level rearrangements during the phase transition.

    Shear-induced grain boundary migration at the atomic level is still not well understood. Here the authors combine in situ shear testing experiments and molecular dynamic simulations to reveal the atomistic mechanism of disconnection-mediated GB migration in different gold nanostructures.

    An ordered structure that has only translational periodicity in one direction— unlike the known solid categories of crystal, quasicrystal and amorphous— is discovered in MgO and Nd2O3 ceramics.
