The basis of a solid-state diode laser is, of course, the diode. Laser diodes can have different emission wavelength—most of them have between 405 nm to 808 nm. The diodes usually have TO3, TO5, TO9, ...

We’re all familiar with semiconductor devices, and we should remember the explanation from high-school physics classes that they contain junctions between two types of semiconductor material. “N” type ...

A diode is a device that allows electric current to flow in only one direction, from its anode towards its cathode but not the other way around. There is plenty of online material explaining diode ...

A semiconductor diode is an electronic component that allows current to flow in only one direction, acting like a one-way valve for electricity. It is commonly used for voltage regulation, converting ...

Psst… Wanna make a canning jar diode? A tennis ball triode? How about a semiconductor transistor? Or do you just enjoy sitting back and following along an ...

Researchers at the University of Georgia and at Ben-Gurion University in Israel claim to have demonstrated how nanoscale electronic components can be made from single DNA molecules. “For 50 years, we ...

A recent forum post reminded me of a common issue we see here at Screaming Circuits – ambiguous diode polarity marking. To start with, some diode manufactures mess with our heads where polarity ...
