It's also used in the semiconductor industry, where it measures the concentration of dopants in silicon wafers. (sciencedaily.com)
These co-crystals function in the role of dopant in place of the actual, pure doping molecules in such systems. (sciencedaily.com)
Although the device has a diode - like structure, its light - emitting system is not based on a diode system, which are made from layers of semiconductors, materials that act like a cross between a conductor and an insulator, the electrical properties of which can be controlled with the addition of impurities called dopants.
