DENA Explained
Questions for the futurePoly(para-phenylene) “PPP”
§DENA or
the Directed Electrochemical NanowireAssembly is a
way of growing nanowiresbetween the tips of two
electrodes
§Electrolytic
substances form shields of ions around electrodes when a voltage is applied to
the electrodes
§ This shield acts to negate the
voltage applied
§When one
of those ions deposits on the electrode, a hole is formed in the shield
§This
hole allows a long range component of the voltage to survive, defining a path
for the nanowireto grow along
