Transmission electron microscopy and cathodoluminescence studies of extended defects in electron-beam-pumped Zn(sub 1-x)Cd(sub x)Se/ZnSe blue green lasers

Results of studies conducted on extended defects in electron-beam-pumped Zn(sub 1-x)Cd(sub x)Se/ZnSe blue and blue-green laser structures are presented. Thin foil samples were sequentially investigated using transmission electron microscopy (TEM) and cathodoluminescence (CL) microscopy to establish a direct correlation between the local luminescence properties and the presence of structural defects. Nonradiative defects by CL were observed with no extended defect counterparts in TEM.
