Semiconductor technologies that drive electronic appliances and devices such as TV displays, computers, tablets, and cell phones have been evolving rapidly. The pursuit of lightweight, thinner, high image resolution, energy-saving displays, and devices have encouraged scientists around the world to find new materials and its combinations to follow-up with those needs. In this respect, organic semiconductors have been extensively studied in the last two decades because of their versatility, low processing requirements, flexibility, and environment-friendly characteristics. Unlike inorganic materials, organic semiconductors do not exhibit a periodic atomic arrangement, and charge transport occurs along their carbon backbones with conjugated bonds. In this chapter, the structural characteristics, classification, conduction phenomena, and optical properties of polymers and small molecules are presented. Organic photovoltaic devices, thin-film transistors, and organic light-emitting diodes are the most common application of these materials, and their most important features are explained. A concise summary of the most commonly used vapor and solution processing techniques for organic semiconductor deposition is presented.
