The third reason is attributed to our innate interest in functional interfaces
between the man-made non-living matters and the living matters, the most important
of which is the human body. The information in the man-made world is stored and
processed electronically while that in the human body is stored and processed chemi-
cally or electrochemically. The electrochemical processes must play an important role
in enabling the technology for direct exchange of information between the two worlds.
In this regard, silicon, which is already the dominant material for processing electronic
information, seems to be a natural candidate as the electrode material on which such
interfaces could be investigated and developed. The processes to deposit organic mol-
ecules such as amino acid and proteins on silicon that can functionally bond to cells
and live tissues and the characterization for the electrochemical properties of these
silicon/bio-material interfaces should be an interesting research area in the future.

New interests and deeper questions, which may still be beyond the imagination
at this time, will surely continue to emerge in the future. There are more interesting
questions, on silicon electrodes to be researched now than before. In some ways, what
has been accomplished is just a preparation for the greater research challenges that lay
ahead, which must be atomistic in detail, complex in the relationships among phe-
nomena and variables, and integral in scope to relate the events at the atomic scale with
the phenomena at a macro scale.
