Outline of Final Research Achievements

Organic semiconductors of C8-BTBT and PTCDI-C8 layers were prepared on C, A, R- single crystal aluminum oxide and (111), (100)-MgO substrates by a vacuum evaporation technique to develop the techniques for controlling the preferred orientation of organic semiconductors. Both the C8-BTBT and PTCDI-C8 layers prepared on single crystal substrates showed characteristic spot X-ray diffraction patterns without any debye rings, suggesting the formation of oriented C8-BTBT and PTCDI-C8 layers irrespective of the substrate materials and orientation.
