| Outline of Final Research Achievements |
In order to realize current injected organic semiconductor lasers, we develop the formation processes of double-hetero structures and improvements of electro-luminescence properties in thiophene/phenylene co-oligomers (TPCO) crystalline organic semiconductor system. To form the multi-layer structures with organic single crystalline properties, we develop the slide boat method, which is utilized in inorganic semiconductor systems and explore the condition for the single crystalline double-hetero structure formation in TPCO semiconductors. We have evaluated the condition for making the crystalline film formation by using the laser spectroscopy and succeeded the optical pumped lasing in the double-hetero structures. We also adopted the doping technique to form the pn junction of organic semiconductors and succeeded the low resistivity film formation by using the deposition method in TPCO organic semiconductors.
