| Research Abstract |
We have attempted to fabricate highly-oriented organic thin films such as copper phthalocyanine, tetrathiafulvalene-tetracyanoquinodimethane (TTF-TCNQ), and pentacene by the use of vicinal substrates, oblique evaporation technique, and rubbing method. As a result, we have succeeded to realize highly flat TTF-TCNQ thin films with the power factor of 7.8×10^<-7> W/mK^2. In addition, the iodine-doped pentacene thin films shows the higher power factor of 2×10^<-5> W/mK^2.
