• EELS mapping on a Si device

    With K2 direct electron detector and fast hardware synchronizing, elemental maps can be acquired in just a few minutes.

  • ELNES mapping on a Si device

    The subtitle change on the edge structure due to different valence states can be resolved by electron-loss near edge structure (ELNES) mapping.
