△ [7a-A203-7] Fabrication of Field Effect Transistors using Oriented Thin Films of Alkyl-substituted Phthalocyanine and Electrical Anisotropy based on Columnar Structure
Keywords:Oriented thin film, Alkyl-substituted phthalocyanine, Field effect transistor
Field effect transistors using molecular oriented thin films of non-peripherally alkyl-substituted phthalocyanine (C6PcH2) were fabricated by the bar-coating method. The thin films were confirmed to be uniformly oriented in a large area by the polarized optical microscopy and a low surface roughness at a molecular level by the atomic force microscopy. The field effect mobility parallel to the column axis was approximately 8 times higher than that perpendicular to the column axis. The experimental result was ascertained to be consistent with the simulated result by the density functional theory calculation.
