Solution-liquid-solid (SLS) growth of ZnSe-ZnTe quantum wires having axial heterojunctions.
Heterostructured ZnSe-ZnTe quantum wires are grown by the solution-liquid-solid (SLS) mechanism. The nature of the axial or radial heterostructure obtained is strongly influenced by the growth sequence and related synthetic conditions. Compositionally graded ZnSe(x)Te(1-x) wires, ZnSe-ZnTe axial heterostructures containing a ZnSe(x)Te(1-x) transitional segment, ZnSe-ZnTe wires with sharp axial heterojunctions, and radial core-shell ZnSe-ZnTe quantum wires have been selectively prepared. The axial and radial quantum-wire heterostructures are characterized microscopically and spectroscopically.
