High-performance ambipolar light-emitting transistors (LETs) of highly photoluminescent α,ω-bis(biphenylyl)terthiophene single crystals exhibit high hole and electron mobilities. The electroluminescence is confined inside the single-crystal channel and emits solely from its edges. A current-density-dependent spectral evolution is observed. This suggests that ambipolar LETs from organic single crystals are a promising route for electrically driven organic laser realization.
