Three-dimensional lattice of parallel-oriented tellurium nanoclusters in an opal matrix

Transmission electron microscopy has been used to study the structural state of tellurium introduced into the voids of an opal matrix from a melt under pressure. It is shown that when the opal is a single crystal (the SiO2 spheres form a close-packed cubic structure), tellurium filling the voids produces an ordered cluster lattice. The tellurium in the clusters has a single-crystal structure whose orientation is conserved in neighboring clusters within an appreciable area. It is thus shown that a lattice of parallel-oriented nanoclusters can be obtained in principle.
