Abstract
Organic thin film transistors having improved properties (e.g., on/off ratio>10.sup.5 at 20.degree. C.) are disclosed. The improved transistors comprise an organic active layer of low conductivity (<5.times.10.sup.-8 S/cm at 20.degree. C., preferably less than 10.sup.-8 or even 10.sup.-9 S/cm). A method of producing such materials is disclosed. Rapid thermal annealing was found to have beneficial results. An exemplary and preferred material is .alpha.-hexathienylene (.alpha.-6T). The improved transistors are expected to find use for, e.g., active liquid crystal displays and for memories.
