WebDec 1, 2024 · The GaInP/GaAs/Ge triple-junction solar cells (3JSCs) can efficiently absorb the broad spectrum of sunlight, and have been widely used in aerospace as the long-term power resource for their high photoelectric conversion efficiency, light weight, stable structures, and low cost [1], [2], [3]. Webon GaAs substrates, the gallium and arsenic components, along with the dopants are heated in separate cylindrical cells. Colli- mated beams of these constituents escape into the vacuum (-10-lotorr) and ark directed onto the surface of the substrate. The rates at which these atomic beams strike the surface can be ...
WebThe GaAs/AlGaAs heterostructure and two-dimensional electron or hole system It is possible to confine electrons (or holes) in a two-dimensional (2D) layer (a 2D electron gas, called a 2DEG, or, for holes, a 2DHG) in a crystal, in such a way that they can move within that layer with minimal scattering. WebAug 1, 1980 · Abstract. The bandgap energy of InGaAsP quaternary alloy lattice-matched to InP has been precisely determined by electroreflectance (ER) measurements. The ER spectra show the typical low-field ER lineshape over the whole alloy composition range, and this has enabled us to determine the precise bandgap energy of the InGaAsP alloy easily.
