Web4 jun. 1998 · The Al x Ga 1−x As/GaAs heterostructure system is potentially useful material for high‐speed digital, high‐frequency microwave, and electro‐optic device applications. … WebGaAs/GaSb tandem cells stacks have been irradiated by 3 MeV electrons. BOL efficiency of the cells for this experiment was 25.5 – 26.2% (AM0, 100 suns). The 17.5% EOL efficiency and 0.68 remaining factor of efficiency have been recorded in the GaAs/GaSb tandem after 1·1015cm-23 MeV electron exposure (Fig. 8).

GaAs was first created by Goldschmidt and reported in 1929, but the first reported electronic properties of III–V compounds as semiconductors did not appear until 1952 [1]. The GaAs crystal is composed of two sublattices, each face centered cubic (fcc) and offset with respect to each other by half the diagonal of the fcc cube. This ...
