CHAMPS is a modular microgravity research furnace developed for the National Research Council' s Space Division. It was flown in a Get-Away-Special(GAS) container aboard the space shuttle STS-67 in June 1993 to investigate GaAs [gallium arsenide] crystal growth by liquid phase electroepitaxy(LPEE). Combining the advantages of both dedicated and generic experimental facilities, CHAMPS allows investigators to specify their own experimental configuration while at the same time providing them with generic peripherals. Configurable hardware included thermal and gradient furnace, levitator, etc., while generic peripherals included control and data acquisition, thermal insulation, and ground support equipment. 2, record 7, English, - configurable%20hardware%20for%20multidisciplinary%20projects%20in%20space

Semiconducteur composé de deux éléments, dont l'un appartient au groupe III du tableau périodique (p.ex. gallium) et l'autre au groupe V (p.ex. arsenic). Il existe également des composés II-VI (p.ex. zinc-soufre). [Source : Rodot-Dupas, p. 11] 2, record 14, French, - compos%C3%A9%20III%2DV

The heterostructure laser. Heterostructures have been crucially important for the development of semiconductor lasers.... Alferov was the first to succeed in producing a lattice-adapted heterostructure(AIGaAs/GaAs, 1969) with clear borders between the layers. Alferov's research team succeeded in rapidly developing many types of components built up of heterostructures, including the injection laser which Alferov patented in 1963. A technological breakthrough occurred around 1970 when heterostructure lasers became able to work continuously at room temperatures. These properties have, for example, made fibre-optic communications practically possible. 2, record 15, English, - heterostructure

[...] la durée de vie utile d'un laser à semi-conducteur est plus longue quand on limite la quantité d'électricité qui le traverse. Il existe plusieurs façons de limiter le courant électrique. On peut, par exemple, introduire d'autres éléments chimiques dans le cristal, de sorte que la couche active du laser soit située entre des matériaux dont la bande interdite est particulièrement large. On obtient ainsi une "hétérostructure" dont les barrières d'énergie internes empêchent la diffusion des porteurs de charge hors de la région active.
