| Research Abstract |
In this study, we aimed to develop a technique to fabricate electronic devices using organic molecular crystals. One of the backgrounds of this study is the report on "superconductivity" for the FET devices fabricated on molecular crystals (Shun et al., Nature, 406, 702 (2000)). We have also followed their procedure and try to fabricate FET devices using various organic crystals as substrates. However all the attempts are failed. Moreover, this report was completely denied later.
Then we changed the research plan to fabricate the organic thin-film devices, and have done following research works.
i)"The study on a photo-switching device fabricated from phthalocyanines soluble to organic solvents"
We fabricated thin films from an acetone solution containing [(n-C_7H_<15>)_4N]_2[Fe^<II>(Pc)(CN)_2]. The fabricated films exhibit the photoswitching phenomenon for UV irradiation.
ii)"The study on a light-emitting diode fabricated from horse-heart cytochrome c"
We fabricated a light-emitting diode from biomolecule and measured the electro-luminescence (EL) spectra.
In addition to these studies, we have studied giant negative magnetoresistance in [Fe(Pc)(CN)_2] salts, and charge-ordering phenomena in various molecular conductors.
