Abstract :
Summary form only given GaInP-AlGaInP is a very promising material for optoelectronic components for the visible spectral range down to 630 nm. Depending on the growth parameter MOVPE-grown AlGaInP alloys (lattice matched to GaAs substrate) show a self ordering in form of a GaP-InP superlattice along the [111] directions. This implies significant changes of the band structure and the optical and electrical properties. We have studied the polarization dependence of the electroabsorption (Franz-Keldysh effect) in AlGaInP-GaInP p-i-n double-hetero structures.
