Modeling, Fabrication and Characteristics of Novel (PVA-SiC-In2O3) Nanohybrid Structures for Optoelectronic Applications

In this article, new films of polyvinyl alcohol (PVA) doped with nanomaterials of silicon carbide (SiC) and indium oxide (In2O3) were prepared as a promising nanocomposites for use in many optoelectronics applications. The PVA-SiC-In2O3 nanocomposites' optical, electrical and structural characteristics were investigated.The properties of the structure including optimization, optical microscopeand FT-IRwere also investigated. The optical microscope showed the good distribution of SiC-In2O3 within the PVA matrix. Although the FTIR results indicated that there was no chemical bond formed between the polymer and the nanomaterialwhich was reflected and demonstrated in a high way the good compatibility and coordination when conducting electronic simulations of the compounds under study in terms of decreasing the values of ionization energy and electron affinity. The energy gap of pure PVA films was (4.5 eV) and its decreased with the addition of SiC-In2O3 nanomaterial reached of 4 eV, 3.9 eV and 3.5 eV for contents 1.2 wt
