Researchers have created a diode out of a 1 nm-sized single molecule with high rectification ratios. Diodes, commonly used in in everyday electronic devices, allow current to flow in one direction ...

This file type includes high resolution graphics and schematics. LEDs are the most efficient way to turn an electric current into illumination. When a current flows through a diode in the forward ...

In a previous article, we explored the behavior of an LED diode as a small light source. We have seen how important a protection resistor is to light up this component. In this article, we will ...
