| 中文摘要 | raman spectra of (gaas)n1/(alas)n2 ultrathin-layer superlattices were measured at room temperature and under off-resonance conditions. the experimental results show that there are two effects in ultrathin-layer superlattices: the confinement effect of lo phonons and the alloy effect. it is found that the relative intensity of the disorder-activated to mode can give a measure of the alloy effect. the raman spectra of one-monolayer superlattices measured in various scattering configurations are very similar to those of the al0.5ga0.5as alloy, and thus the alloy effect is prominent. however, in the case of monolayer number n greater-than-or-equal-to 4, the confined effect is prominent, while the alloy effect is only shown as an interface effect. |
