| Outline of Final Research Achievements |
The preferred orientation and growth mechanism of single and bi-layers of C8-BTBT (2,7-dialkyl[1]benzothieno[3,2-b][1]benzothiophenes) and PTCDI-C8 (N,N’-dioctyl-3,4,9,10-perylene tetracarboxylic diimide) were investigated for developing the high-performance organic semiconductor electronics. The C8-BTBT and PTCDI-C8 layers possessed the (001) preferred orientation irrespective of the substrate material and orientation, preparation condition and the thickness, single layer or bi-layer, and the oriented continuous single and bi-layers were formed by the coalescence of the oriented islands with the flat top surface.
