Semiconductors confined in zeolite
- Argonne National Lab., IL (United States); and others
Clusters of the elemental semiconductor Se and compound semiconductors RbSe and CsSe have been incorporated in Nd-substituted Y-zeolite by vapor diffusion techniques. TEM measurements indicate that the semiconductor material resides principally within the cage structure of the zeolite host, while high-resolution neutron and x-ray powder diffraction show that the clusters are out of registry with the zeolite host. Measurements of the radial distribution functions with anomalous x-ray scattering suggest that the short-range structures of the clusters are similar to those of the bulk liquid measured by neutron diffraction, with Se{sub 2}{sup 2-} Zintl ions surviving in the clusters of the compound semiconductors.
