Description

The use of the binary and quaternary systems InP and In1-xGaxAs1-yPy for the fabrication of long wavelengths (i.e., 1.3-1.6μm) 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 μm. 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 (∼10-9 Torr)
