History With the invention of the transistor around the middle of the last century, inorganic semiconductors such as Si or Ge began to take over the role as the dominant material in electronics from the previously dominant metals. At the same time, the replacement of vacuum tube based electronics by solid state devices initiated a development which by the end of the 20th century has lead to the...

متن کاملCharge transport in organic semiconductors.
Modern optoelectronic devices, such as light-emitting diodes, field-effect transistors and organic solar cells require well controlled motion of charges for their efficient operation. The understanding of the processes that determine charge transport is therefore of paramount importance for designing materials with improved structure-property relationships. Before discussing different regimes o...
متن کاملOrganic semiconductors for organic field-effect transistors.
The advantages of organic field-effect transistors (OFETs), such as low cost, flexibility and large-area fabrication, have recently attracted much attention due to their electronic applications. Practical transistors require high mobility, large on/off ratio, low threshold voltage and high stability. Development of new organic semiconductors is key to achieving these parameters. Recently, organ...
متن کاملWednesday CPP 24 : Organic Semiconductors
The contact resistance is known to severely hamper the performance of organic thin-film transistors. This is particular true when dealing with large injection barriers, high mobility organic semiconductors, or short channel lengths. A common assumption is that the primary quantity determining the value of the contact resistance is the injection barrier at the source electrode. Using drift-diffu...
