LaPierre Física, Astronomía y Matemáticas Plasmons Superlattices Raman scattering The formation of the miniband electron energy structure was explored in doped InGaAs=InP superlatticeswith different periods. The analysis of the Raman data allowed us to conclude that in spite of the defect structureof the layers constituting the superlattices, their super-periodicity was well defined. The quantitative proofof the conditions for break-down of the Raman selection rules is presented: the emergence of the selectionrules of the coupled plasmon-LO phonon vibrations was demonstrated to occur due to the increase of theircoherence lengths. In addition, the expected anisotropy of the effective electron masses was found by high-fieldmagnetoresistance. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436528 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3B Vol.36 |
