Charge Carrier Injection (Generation) Mechanism in Organic Field Effect Transistors and Organic Solar Cells

[attachment=18326]


What is a Polymer?

A Long molecules made up from lots of small molecules called monomers

A polymer is a large molecule(macromolecule) composed of repeating structural units.

Doping involving no Dopant ions*Charge Injection Doing

Charge Injection mechanism is most Conveniently carried out using a Metal/insulator/Semiconductor(MIS) Configuration .It is involving a metal and a conducting Polymer separated by a Thin layer of High Dielectric strength insulator
Superconductivity: Polythiophene .
Surface charge layer and accumulation layer will be investigated

Organic Field effect Transistors (OFETs)

Organic transistors are transistor that use organic molecules rather than silicon for their active material. This active materials can be composed of a wide variety of molecules
Advantages
Compatibility with plastic substances
Lower-cost deposition process such as spin coating, printing, evaporation
Lower temperature manufacturing (60-120oC)


Disadvantages

Lower mobility and switching speeds compared to silicon wafers
Local doing is not possible
High Contact resistance
