Fabrication and Analysis of PVA/TiC/SiC Hybrid Nanostructures for Nanoelectronics and Optics Applications

In present work, hybrid flexible nanostructures of titanium carbide (TiC)/silicon carbide(SiC) doped polyvinyl alcohol(PVA) were fabricated as promising nanomaterials to utilize in various optoelectronics applications. The optical, structural, and dielectric properties of (PVA–TiC–SiC) nanocomposites (NCs) films have been investigated. The obtained results indicated that the increasing of TiC/SiC NPs improve the alternating-current(A.C) conductivity, dielectric constant, and dielectric losses of PVA. The dielectric constant and dielectric losses reduced while the A.C electrical conductivity enhancement when the frequencies increased. The results of optical properties showed the absorbance of pure PVA was rise of 98% with adding 6 wt% of TiC/SiC NPs and the optical conductivity increased of 99%, this performance is benefit for photocatalysis, diodes, optoelectronics, and solar cells applications. The energy gap reduced for allowed and forbidden transitions approximately 86% and 73%, respectively, with adding 6 wt% of TiC/SiC NPs. By adding of TiC/SiC NPs, the other optical factors of (PVA–TiC–SiC) nanocomposites were improved with a broad range of photon energy and this make them as potential nanomaterials for photonics applications. Finally, the findings showed that (PVA–TiC–SiC) nanostructures are attractive materials for promising optoelectronic nanodevices.
