Query: Can Ballistic Electrons Probe the Electronic Spectra of Individual
  Buried Molecules?   A theoretical study is presented of the ballistic electron emission spectra
(BEES) of individual insulating and conducting organic molecules chemisorbed on
a silicon substrate and buried under a thin gold film. It is predicted that
ballistic electrons injected into the gold film from a scanning tunneling
microscope tip should be transmitted so weakly to the silicon substrate by
alkane molecules of moderate length (decane, hexane) and their thiolates that
individual buried molecules of this type will be difficult to detect in BEES
experiments. However, resonant transmission by molecules containing unsaturated
C-C bonds or aromatic rings is predicted to be strong enough for BEES spectra
of individual buried molecules of these types types to be measured. Calculated
BEES spectra of molecules of both types are presented and the effects of some
simple interstitial and substitutional gold defects that may occur in molecular
films are also briefly discussed.
