Ultralow-voltage electrochemical organic light-emitting transistors with pinned and wide lateral recombination (opens in new tab)  🔌electronic circuit

Light emission from organic transistors holds strong potential for user-interactive functionality across applications ranging from wearable and biointegrated systems to neuromorphic electronics. However, conventional single-active-layer organic transistors suffer from inefficient charge carrier injection, resulting in high drain voltages (>80 V in field-effect devices and >3.5 V in electrochemical devices with p–i–n junctions) and narrow, spatially dynamic recombination zones (<75 μm). Here w...
