It took more than 150 years for American and British suffragists to gain women’s right to vote—decades filled with struggle, sacrifice, and fervent attempts to sway public opinion. And those efforts ...

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 ...

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 ...

Inorganic LEDs are light-emitting diodes (LEDs) made from a crystalline semiconductor. The optical emission wavelength can be selected by varying material composition. Example active regions include ...

Abstract: The capability to fabricate printed and flexible energy harvesting and conditioning circuits, over a large area and with low-cost techniques, is crucial to enable flexible and wearable ...

Abstract: In this work, high-performance GaN vertical Schottky barrier diodes (SBDs) are successfully fabricated on the GaN-on-GaN substrate by using the self-alignment trench structure and argon (Ar) ...
