Abstract
The properties of ZnSe epilayers fabricated by molecular beam epitaxy on lattice-matched InxGa1-xAs buffers grown on GaAs(001) substrates ha ve been investigated by means of photoluminescence spectroscopy and tr ansmission electron microscopy. For suitable values of x and ternary-l ayer thickness, the partial character of the strain relaxation within the III-V layer can be compensated for, minimizing the residual strain in the ZnSe overlayer. Large reductions in the dislocation density an d Y-line emission as compared to conventional ZnSe/GaAs heterostructur es can be reproducibly obtained.
