DETERMINATION OF THE BAND-STRUCTURE OF DISORDERED ALGAINP AND ITS INFLUENCE ON VISIBLE-LASER CHARACTERISTICS

Using hydrostatic pressure techniques, we have obtained new energies f or the X-minina, L-minima and band offsets in GaInP-AlGaInP, Theoretic al calculations of the threshold current density in bulk and strained quantum-well visible lasers are shown to be in good agreement with exp erimental results, obtained as a function of both temperature and hydr ostatic pressure, Our results show that heterobarrier leakage current is a dominant limiting factor in the performance at shorter wavelength (similar to 635 mm) operation, but is of less significance for longer wavelength (similar to 675 mn) operation,
