Polymer Electronics
(A tutorial)
Polymer:  A chemical compound or mixture of compounds formed by polymerization and
consisting essentially of repeating structural units

Electronics:  A branch of physics that deals with the emission, behavior, and effects of
electrons (as in electron tubes and transistors) and with electronic devices

In constructing a polymer electronic device we are fundamentally interested controlling
the flow of energy
   · Where and how it is absorbed
   · Where and how it flows
   · Where and how it is emitted
     Also:  How the device interacts with the environment around it

There are now many different types of polymer based electronics:
Transistors, Light Emitting Diodes, Photovoltaic, Sensors are just a few examples.

To fully understand and appreciate the difficulties with polymer based electrons we first
need to review more conventional device technologies (i.e., metals, oxides and
inorganic semiconductors).
