| Research Abstract |
We have developed light-emitting field-effect transistors in which a high-quality slab crystal of thiophene/phenylene co-oligomer is incorporated. Using these devices we intended to achieve the current-injected laser oscillation. We observed spectrally-narrowed emissions from the devices when the said device was equipped with a one-dimensional or two-dimensional resonator or diffraction grating. The spectrally-narrowed emissions can be regarded as a precursor phenomenon of the laser oscillation. In particular, we have confirmed exceedingly intense emissions accompanied by an exceptionally narrowed emission lines.
