摘要：The dielectric constant of the thin films of CdS nanoparticles grown in polymer matrix (PVA) deposited on Si substrates has been studied at room temperature as a function of frequency under vacuum (10 -3 Torr). The samples of CdS nanoparticles have been prepared with different particle sizes and dispersibilities ( . ) by varying the chemical bath deposition temperature. The room temperature dielectric constants of the CdS-PVA composites lie in the range 120 to 255 at high frequency range (>1 kHz) which are much higher than that of only PVA having dielectric constant ~28 and CdS having dielectric constant 8.9. The dielectric constant of the films increases with the decrease of particle size.
