| Outline of Final Research Achievements |
The purpose of this project is to utilize a unique feature that asymmetric rod-like organic molecule composed of pi-electron skeleton linked with alkyl chain affords extremely uniform and ultrathin single crystal layer based on the formation of molecular bilayer structure as is similar to the cell membrane. We focus on the ultrathin insulating layer formed by the alkyl chains within the layer, and investigate the possibility to apply it for device functions. We fabricated highly uniform Ph-BTBT-C10 single-crystal thin films with controlled layer-number thickness of molecular bilayers, and studied the interlayer conductivity of the single crystal layers. As a result, we found that the alkyl-chain layer formed within the molecular bilayer structure becomes the origin of anomalous carrier transport characteristics associated with the tunneling-based large interlayer access resistance.
