Charge Transport Study Of Doped Polymer Thin-film Transistors

Organic semiconductors and electronic devices based on these materials continue attracting great interest due to their excellent and unique optoelectronic properties as well as the advantageous possibilities of realizing flexible, light-weight, low-cost, and transparent optoelectronic devices fabricated on ultra-thin and solution-processable active layers. However, their poor electronic performance and unstable operation under ambient conditions limit their application in consumer electronics. This book encompasses the doping work performed for the improvement of the electrical performance of organic thin-film transistors by doping and understanding the fundamental principles and underlying mechanisms of the molecular doping of polymeric semiconductors. Chapters 1 and 2 present a common introduction and background to organic semiconductors and organic field-effect transistors as well as a brief comparison of organic and inorganic semiconductors. The description of the issues regarding charge carrier transport and other optoelectronic properties of organic semiconductors is also provided.
