Ultranarrow ZnSe nanorods and nanowires: Structure, spectroscopy, and one-dimensional properties

Uniform ZnSe ultranarrow nanorods (1.3 nm x 4.5 nm) and 100-200 nm long nanowires with the same width have been produced and characterized, and the spectroscopic properties measured. The uniformity of the rods and wires is demonstrated in their spontaneous assembly into highly ordered 2D super-crystals (see Figure). Development of the rods from more spherical nuclei is demonstrated.
