A special type of diode made from a crystalline material whose layers are just three atoms thick has been successfully realized for the first time. The superior properties of such ultra-thin crystals ...

A physicist has made the best ever p-n junction diode from a carbon nanotube. The current-voltage characteristics of the device exhibit an "ideality factor" of one, which is the maximum possible value ...

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 ...

Diodes allow directed flows of current. Without them, modern electronics would be inconceivable. Until now, they had to be made out of two materials with different characteristics. A research team has ...

A diode made of a self-assembly monolayer with ferrocenyl termini shows an on/off ratio of ∼10 5. Figure 1: Limitations and opportunities for the on/off current ratio in nanometre-scale devices. The ...

Power diodes are a necessary component of all electronics, and are made of a semiconductor material — in most cases silicon — that conduct electrons in one direction. Transphorm’s power diodes are ...

How to replace MOSFETs with load switches, and the impact of on-resistance. Swapping out diodes with ideal diodes, and the use of ideal-diode controllers. Why replacing fuses and resettable fuses with ...
