This ETH Zurich logo consists of 2,800 nano light-emitting diodes and, at a height of 20 micrometers, matches the size of a human cell.Amanda Paganini / ETH Zurich Swiss researchers have built organic ...

A process developed at ETH Zurich enables the massive miniaturisation of organic light-emitting diodes (OLEDs) in only one single step. The light sources are now smaller than the wavelength of the ...

Abstract: The key difficulty for energy harvesting technique at passive Internet of Things (IoT) scenarios is that the operation and efficiency of a rectifier is limited by weak ambient signals. In ...

We might tend to take the word “diode” for granted if we’re thinking of a “diode” as just a two-lead or two-terminal device that gets used in this or that place for this or that purpose. It can become ...

Researchers have discovered the mechanism for supercurrent rectification, in which current flows primarily in one direction in a superconductor. By using a specific iron-based superconductor, they ...

What would happen if you combined the unparalleled efficiency of a superconductor with the flexibility and controllability of a semiconductor? Thanks to a new breakthrough in quantum materials, we may ...

For power measurements in wireless telephony and high-speed data communication systems, the Schottky diode is the predominant choice. Current and voltage are indeed important, but power gives us a ...

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 ...

In any electronic circuit, the energy stored in an inductor must be properly channeled in the event of switching. This FAQ explains how a freewheeling diode can help achieve smooth inductor ...

SPICE circuit simulations are a powerful design tool to analyze a system's immunity against conducted EMI surge voltages. SPICE can serve as a valuable tool to validate and optimize the performance of ...
