| 中文摘要 | An attempt has been made to explore the possibility of constructing, according to certain design requirements, a graded band-gap barrier by gradient period (AlAs)n/(GaAs)m superlattice with n and m varying in the range from 1 to 9 monolayers. Photoreflectance spectra show a series of oscillations which are attributed to Franz-Keldysh oscillation induced by quasielectric field in the gradient period superlattice regions. It indicates that a graded band gap is formed in this structure. The slope of the band gap in the graded region determined experimentally from the energy of the extrema of this oscillation is in good agreement with theoretical prediction. |
