For the first time, researchers in China have demonstrated a high-temperature superconducting diode effect, which allows a ...

Discover the science behind diodes — the tiny components that control the flow of electricity. Learn how they let current ...

I n an idealized diode, no reverse current flows from cathode to anode when the device is reverse-biased. However, with real-world diodes, large amounts of stored charge can flow from the cathode—back ...

A model of a quantum thermal diode based on a qubit and qutrit. The asymmetric design allows this system to behave as a thermal diode when connected between two thermal baths. Credit: APL Quantum ...

A single-molecule diode with the highest on–off current (or rectification) ratio to date has been unveiled by a team of physicists and chemists in the US. While single-molecule diodes have been made ...

Apart from the sun, solar power systems cannot work without a reflow protection diode between the solar panel and the energy store. When current flows into the store, there is a potential drop across ...

How a Virginia Tech research team constructed its novel thermal diode. Test results of the thermal diode. Electrical engineers are obviously very familiar and comfortable with the basic diode, a ...

What Is A Light-Emitting Diode? A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. LEDs function by converting electrical current into ...

An ultra-low-power neural device that operates by controlling the flow of ions instead of electrons, unlike conventional semiconductor-based devices, has been developed. It is up to 50 times more ener ...
