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 ...
Diode lasers are electrically driven lasers generally made from semiconducting materials. In addition to the optical considerations common with all semiconductors, diode laser structures must also ...
Organic LEDs are light emitting diodes (LEDs) that use polymers or small organic molecules as their optically active element. Development of organic LEDs is driven in particular by its potential as a ...
