HL 17: Focussed Session: Atomic Scale Characterization

Dienstag, 13. März 2018, 09:30–13:00, EW 202

For a detailed understanding of complex semiconductor nano- and heterostructures as well as the physics of devices based on them, a systematic determination and correlation of the structural, chemical, electronic, and optical properties on a nanometer or atomic scale is essential. This session brings the atomic structural and chemical imaging using scanning tunneling microscopy, atomic probe tomography, and ultra-high resolution transmission electron microscopy together with the nanoscopic mapping of the optical and electronic properties using scanning transmission microscopy cathodoluminescence spectral imaging.
