H. Peyre et al., NONDESTRUCTIVE APPROACHES TO INTERDIFFUSION PHENOMENA ACROSS GAINAS GAINASP INTERFACES - PHOTOLUMINESCENCE VS RAMAN/, Materials science & engineering. B, Solid-state materials for advanced technology, 20(1-2), 1993, pp. 73-76
We report a cross investigation, performed on the same series of sampl
es, of the effect of interdiffusion on the photoluminescence and Raman
spectra of a prototype structure made of a single GaInAs/GaInAsP quan
tum well (QW). Provided careful analyses are done, we find that both m
ethods of investigation can be used with reasonable agreement.
