Fundamental study on fabrication of highly-oriented organic thinfilms with high thermoelectric performance

我们尝试利用邻近衬底、斜蒸发技术和摩擦方法来制备高度取向的有机薄膜，如铜酞菁、四硫富瓦烯-四氰基喹二甲烷(TTF-TCNQ)和并五苯。结果，我们成功地获得了功率因数为7.8×10~(-7)W/mK^2的高平坦度TTF-TCNQ薄膜，掺碘并五苯薄膜的功率因数达到了2×10~(-5)&gt；W/mK^2。

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.
