| 中文摘要 | a trilayer asymmetric superlattice, si/si1-xgex/si1-ygey, is proposed, in which the broken inversion symmetry makes the microstructure optically biaxial; in particular, inequivalent interfaces in this heterostructure may cause a polarization ratio as large as about 2.5% in the absence of an external field. the electronic structure and absorption spectra for two types of trilayer superlattice with different parameters are calculated by use of the tight-binding model; the findings indicate the importance of the carrier confinement for the anisotropy value. the effect of external electric field on the optical anisotropy for such structures has also been discussed, and a pockels coefficient of 10-9 cm v-1 estimated. |
