Résumé
Incorporation of semiconductors into zeolites has been carried out to determine the effect of confinement on structure, dynamics and electrical properties. The semiconductors stabilized in the zeolite supercages, Se, RbSe and CsSe, are known to preserve their semiconducting behavior upon melting. Examination of the polycrystalline materials by TEM, Raman and anomalous X-ray diffraction show interesting behavior which is compared with that of the bulk materials of the guest species.
