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 ...
Abstract: This letter presents a 335-GHz quadrature mixer with monolithic microwave integrated circuit (MMIC) utilizing the GaAs Schottky diode technology. By using two identical double-sideband (DSB) ...
Abstract: In-vacuum single electrons counting has been demonstrated with single-photon avalanche diodes without scintillation. An electron detection probability (EDP) of ~70% at 10-keV electron energy ...
