Calculated Valence Electron Density of Silicon Nanocrystal

Caption:

The calculated valence electron density of a silicon nanocrystal. [See also, Atomic Structure of a Silicon Nanocrystal and Excited Electron State of a Silicon Nanocrystal.]

This research was funded in part by National Science Foundation grants DMR 01-02668 and DMR 01-21361.

More about this Image This plot shows where all the electrons tend to be moving within the silicon nanocrystal. Each electron in the molecule exists in a strangely shaped orbit, but when looking at all the electrons and their orbits, the average is this. Note how the plot looks like the electrons form clouds around all the atoms and in between neighboring atoms. This plot shows the bonds that exist between atoms that hold the molecule together.
