Outline of Final Research Achievements

In this study, DiNaphthoThienoThiophene (DNTT), which equips good stability of crystalline and higher mobility, has chosen to produce the organic semiconductor thin-film transistor (organic TFT). At first, the device design has optimized to have higher electric current amplification rates as the transistor. The target of this study is to measure the amplification degree of the drain electric current, the wavelength dependence and the pulse response speed by irradiating photons. This is a first basic study to adopt the organic TFT to an optical sensor with the high-speed pulse response and high photon sensitivity. The results of this study can feed back to produce the measuring instrument including a detector and readout circuit.
