Traditional inverters – NOT gates – are already made with diodes (typically not light-emitting), resistors ... 1 and 1.5V for logic 0. Adding two 1N914 diodes and an AND gate ahead of the ...

In 1962, when he was 33, the scientist Nick Holonyak, Jr., created the first practical visible light-emitting diode. At GE, they called it "the magic one." Someone actually wrote that on the back ...

An upconversion organic light-emitting diode (OLED) based on a typical blue-fluorescence emitter achieves emission at an ultralow turn-on voltage of 1.47 V. The technology circumvents the ...

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 ...

and the recent introduction of LED (light emitting diode) bulbs has increased the amount of light coming from cities by a considerable amount. A global study led by Christopher Kyba from the GFZ ...
