SEMICONDUCTORS IN THE DISORDERED STATE - FROM BULK TO NANOSCALE

Incorporation of semiconductors into zeolites has been carried out to determine the effect of confinement on structure, dynamics and electri cal properties. The semiconductors stabilized in the zeolite supercage s, Se, RbSe and CsSe, are known to preserve their semiconducting behav ior 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.
