Field-effect transistor with at least two different semiconductive organic channel compounds

摘要

A field effect transistor has a channel between a source electrode and a drain electrode made from an organic semiconductor. In one form of the invention, the channel is a mixture of at least two different organic compounds. In another form of the invention, the channel is a lamination of at least two films of different organic compounds. The channel can also be a pi -conjugated block copolymer of at least two different types of monomers.
