What is CdTe/CdMnTe lateral superlattices grown on (0 0 1) C vicinal substrates about?

We have investigated the optical properties of quantum wire arrays grown on vicinal surfaces with lateral period of 180 A s . Due to the speci"city of the CdTe, for which the preferential orientations of step edges during the growth are along the (1 0 0) direction, vicinal substrates misoriented around the (1 0 0) direction are used. The 1D periodic potential modulation in CdTe/CdMnTe tilted superlattice is evidenced experimentally by the energy redshift of the photoluminescence observed when the superlattice is vertical. Such a behavior of the ground state in the 1D structure is accounted quantitatively by a theoretical approach which uses a sinusoidal modulation potential to describe the lateral con"nement.
