SERVICES PROJECTS PRODUCTS PUBLICATIONS CONTACT User Area Tag - DIODES A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate, in which electrons can flow in only one direction, from cathode to plate. A semiconductor diode, the most common type today, is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. Semiconductor diodes were the first semiconductor electronic devices. SiC Schottky Diodes Reliability Testing for Bepi Colombo by Demetrio Lopez Fabrication technology and packaging strategy for 300V-5A Silicon Carbide Schottky diodes with a wide temperature operation range capability (between -170ºC and 300ºC). These diodes have been designed for harsh environment space applications such as inner Solar System... Evaluation of the Radiation Hardness of GaSbbased Laser Diodes for Space Applications by Juan Barbero ASER diodes are increasingly used for space applications, either to pump solid state lasers, in photonic payloads, or as sources for LIDAR or spectrometric applications. In space applications reliability issues are a primary concern and among them, radiation hardness is one of... Evaluation of 2.1μm DFB Lasers for Space Applications by Juan Barbero Semiconductor lasers (or laser diodes) operating in the wavelength region of 1.8 µm to 3 µm are attractive light sources for applications including remote sensing, laser spectroscopy or pollutant detection. Highly strained InGaAs Quantum Wells (QW) grown on InP substrates can... Reliability Assessment of Medium / Large Area PIN SI Photodiodes for Optical Wireless links for Intra – Spacecraft Communications by Juan Barbero The Reliability Assessment of Area PIN SI Photodiodes was a exhibition theme in the First International Symposium on Reliability of Optoelectronics for Space that took place in Cagliari Italy , between May 11 – 14, 2009.
