Abstract
We have grown by atomic layer epitaxy CdTe/MnTe tilted and serpentine superlattices. These heterostructures are formed by depositing in the step-flow growth mode fractional monolayersuperlattices ( CdTe ) m ( MnTe ) n , with p=m+n∼1, onto 2 °A and 2 °B Cd 0.95 Zn 0.05 Te vicinal substrates. Transmission electron microscopyimages reveal a good in-plane CdTe/MnTe separation and a uniform short-range superlattice period. The very existence of those superlattices imply that Te-based vicinal surfaces present a regular array of monomolecular steps, with no important step meandering and no step bunching.
