A transistor fabricated from the crystalline phase of an organic semiconductor material could provide a path to improved switching speeds — rivalling those of devices built from inorganic materials ...

In 1782, Alessandro Volta was the first to use the term "semiconducting" to describe the electrical properties of certain materials. In 1833, Michael Faraday observed that the resistance of silver ...
