Miniaturization ranks as the driving force behind the semiconductor industry. The tremendous gains in computer performance since the 1950s are largely due to the fact that ever smaller structures can ...

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 ...

A new one-step process miniaturises OLEDs to smaller than their emitted wavelength, enabling precise control of light direction and polarisation for displays, sensors and optical uses. (Nanowerk News) ...

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 ...

This ETH Zurich logo consists of 2,800 nano light-emitting diodes and, at a height of 20 micrometres, matches the size of a human cell. A single pixel measures around 0.2 micrometres (200 nanometres).
