Abstract

The invention relates to a semiconductor device having a semiconductor path made from an organic semiconductor material. Semiconductor particles or semiconductor clusters are distributed randomly in the organic semiconductor material. The semiconductor particles and/or semiconductor clusters can also be linked by linker molecules. The addition of semiconductor particles to the organic semiconductor material makes it possible to improve the electrical properties, for example, of a field-effect transistor has a semiconductor path of this nature.
