This work shows that d.spite a lattice mismatch of almost 20%, Cd.nTe/Cd.e/Cd.nTe heterostructures grown d.rectly on Si(111) have surprisingly good.optical emission properties. The investigated.structures were grown by molecular beam epitaxy and.characterized.by scanning transmission electron microscopy, macro-and.micro-photoluminescence. Low temperature macro-photoluminescence experiments ind.cate three emission band. which d.pend.on the Cd.e layer thickness and.have d.fferent confinement characteristics. Temperature measurements reveal that the lower energy emission band.(at 1.48 eV)is associated.to d.fects and.bound.exciton states, while the main emission at 1.61 eV has a weak 2d.character and.the higher energy one at 1.71 eV has a well-d.fined.(zero-d.mensional, 0d. 0d.nature. Micro-photoluminescence measurements show the existence of sharp and.strongly circularly polarized.(up to 40%) emission lines which can be related.to the presence of Mn in the heterostructure. This result opens the possibility of prod.cing photon sources with the typical spin control of the d.luted.magnetic semicond.ctors using the low-cost silicon technology.
