The diode is operated with a slight forward bias so a regular silicon signal diode (e.g., 1N914) can be used. The output impedance of the circuit is low and the load here has little effect on the ...

Organic laser diodes produce a much purer light enabling additional applications, but they require currents that are magnitudes higher than those used in OLEDs to achieve the lasing process. These ...

Virtually all light-emitting diodes used today require phosphors based on so-called rare-earth elements, which are expensive and challenging to obtain.

The same molecule that provides the instructions for building life may one day be used to build computers. Using copper and a common ingredient of shampoo, scientists were able to turn DNA into a ...
