TL;DR: In this article, a high-performance ambipolar light-emitting transistor (LET) that has high hole and electron mobilities and excellent luminescence characteristics is described, and a conspicuous light-confined edge emission and current-density-dependent spectral evolution are observed.

TL;DR: In this article, the state-of-the-art in the field of crystal laser devices is reviewed and an outlook and personal view is provided on the further developments of laser crystals and their applications.

TL;DR: In this article, the characteristics of organic single-crystal light-emitting field effect transistors (OSCLEFETs) have been discussed, and various single crystal growth methods that produce different morphologies and geometries of crystals are described.

TL;DR: The thiophene/phenylene co-oligomers are ranked as a newly occurring class of organic semiconductors as discussed by the authors and are characterised by that thiophenes and phenylenes are hybridized at the molecular level with their various mutual arrangements.

TL;DR: In this article, the authors developed a method of crystal growth in a liquid phase, which produces directly onto a substrate well-defined polygon organic thin crystals with uniform thickness, and the thin crystals are found to be single crystals of high quality.
