Organic semiconductors with conjugated electron system are currently intensively investigated for applications such as organic light emitting diodes (OLED) and organic solar cells. They offer key advantages, such as flexibility, easy recycling, and low cost. However, much of the basic physics is still not well understood. In this talk, I will discuss first studies of basic doping and transport effects in oligomer organic materials. In particular, I will show that the concept of “band structure engineering” known from inorganic semiconductor unexpectedly also works for organics. Finally, I will discuss some applications including recent work on novel transistor structures achieving record parameters.
