FIELD EFFECT TRANSISTOR AND METHOD OF MANUFACTURING THE SAME

摘要

Provided is a field effect transistor having an organic semiconductor layer, in which the organic semiconductor layer contains at least a tetrabenzo copper porphyrin crystal and has peaks at two or more of Bragg angles (2theta) in CuKalpha X-ray diffraction of 8.4° ± 0.2°, 10.2°±0.2°, 11.8°±0.2°, and 16.9° ± 0.2°, and the tetrabenzo copper porphyrin crystal comprises a compound represented by the following general formula (1) : (Wherein R2's each represent a hydrogen atom, a halogen atom, a hydroxyl group, or an alkyl group, oxyalkyl group, thioalkyl group, or alkylester group having 1 to 12 carbon atoms, and R3's each represent a hydrogen atom or an aryl group.)
