Electron microscopy based studies of catalytically grown semiconductor nanowires

• We give an introduction to modern electron microscopy techniques, applied to semiconductor structures. We concentrate on the analytical capabilities of high resolution transmission electron microscopy (TEM) and luminescence-based analysis, cathodoluminescence, in the scanning electron microscope. For the TEM, we will demonstrate a number of techniques and detection schemes, such as energy dispersive analysis of X-rays, electron energy loss spectroscopy, high-angle annular darkfield, and Fourier and strain mapping. The capabilities of the techniques are illustrated by various semiconductor nanowires (NWs), grown catalytically by gold seed-particles on planar substrates. These structures include homogeneous NWs, heterostructured NWs, core-shell NWs and branched NWs.
