Introduction To Organic Field Effect Devices

This course gives an introduction into the topic of Organic Field Effect Transistors (OFETs), covering the fundamentals of the physics, materials, operation principles and electrical characteristics, as well as device design and fabrication details.

Topics:

• Semiconducting Behavior and Charge Transport in Organic Materials: fundamentals, chemical, molecular, and physical principles, doping, charge transport types in organics
• Materials and Interfaces for Organic FETs: metal-organic semiconductor junctions (contacts), organic and inorganic dielectric materials, MIS-Junctions, inversion in organic MIS structures
• OFET Devices: operation principles, fundamental equations, IV characteristics and regimes, characteristic plots, origins of non-ideal device behavior
• AC-response of OFETs, small signal models, vertical OFET geometries, aspects of OFET fabrication and patterning
