Scanning tunneling microscopy nanocrystals

Fig. 4.4. Scanning tunneling microscopy image of polymer-coated Pdssi nanocrystals. The nanocrystals are seen as fluffy balls against the plane background of the graphite substrate. The inset shows a high-resolution electron micrograph (HRTEM) of an individual...

The prepared films [50] have been characterized with attenuated total reflection Fourier infrared spectroscopy, PL, optical ellipsometry, and scanning tunneling microscopy, and the results are consistent with the formation of stable, disordered monolayers of GdSe nanocrystals with high packing density. This assembly technique may have applications for the production of molecular electronic devices on semiconductor substrates [50].
