Popis: | The use of the binary and quaternary systems InP and In{sub 1{minus}x}Ga{sub x}As{sub 1{minus}y}P{sub y} for the fabrication of long wavelengths (i.e., 1.3-1.6{mu}m) LED's and lasers is a well-established approach. Our work is focused on the quaternay (Q) materials, with the major emphasis being on the surface chemistry of epitaxially grown Q-layers, lattice matched to InP and photoluminescing at about 1.3 {mu}m. In this paper the authors report on a surface stoichiometry shift that has been observed on annealing Q-layers up to about 600{degrees}C in a vacuum ({approximately}10{sup {minus}9} Torr). |
