Outline of Final Research Achievements

We attempted to enhance performance of field-effect transistors with an organic-inorganic hybrid perovskite semiconductor. We obtained a very high hole mobility of up to 26 cm2 V-1 s-1 in p-channel perovskite transistors by optimizing transistor structures. We also demonstrated the first-ever n-channel operation of perovskite transistors with an electron mobility of up to 4.6 cm2 V-1 s-1 through a source-drain electrode modification. In addition, we investigated the optically pumped lasing properties of an organic semiconductor film embedded into an optical resonator. We demonstrated not only quasi-continuous-wave operation with a very high frequency of 80 MHz but also true continuous-wave operation with a very long excitation duration of 30 ms for the devices. These frequency and time are the highest ever reported in any organic laser device.
