| Summary: | 碩士 === 國立交通大學 === 物理研究所 === 100 === This is the first main point of the thesis. It is the first time to apply small molecule material to SCLT by the liquid state process. The small molecule, Spiro-OMeTAD, has high solubility and the HOMO(4.9eV) is match up with MoO3/Al. The Spiro-OMeTAD itself has an advantage which is stable in atmospheric environment, so we successfully fabricate the small molecule SCLT which has the characteristic of transistor. The output current density is 0.07 mA/cm2, on/off current ratio as 70000. In addition to enhance the ability of hole injection, we add a PEDOT：PSS film above the Actice Layer. The output current density is indeed increase, 2.3 mA/cm2, on/off ratio is as 1500. This is the second main point of the thesis.
