The simplest configuration of an organic light-emitting diode (OLED) consists of an organic semiconductor layer sandwiched between two electrodes, the anode ... produce light emission, and the ...
Electrical measurements on these diodes revealed that increasing their temperature from ambient to 573K produces a fall in ...
In fact, Henry Round at Marconi Labs noted the emission of light from a semiconductor diode 100 years ago and, independently, a forgotten Russian genius — Oleg Losev — discovered the LED.
