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 ZnSexTe1-x wires, ZnSe−ZnTe axial heterostructures containing a ZnSexTe1-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.
