Halide semiconductors stand at the very beginning of semiconductor science and technology. CuI was reported as the first transparent conductor, and the first field effect transistor was made from KBr. Although halogens are frequently used in semiconductor preparation, little use is currently made from halide semiconductors in electronics and photonics. We review past reports on the metal halide semiconductor CuI and related alloys and discuss recent progress with regard to this material including its use in organic electronics and solar cells as well as our own work on fully transparent bipolar heterostructure diodes (p‐CuI/n‐ZnO) with high rectification of several 107 and ideality factors down to 1.5. γ‐CuI(111) thin film on glass (1 × 1 cm2) and IV‐characteristics of p‐CuI/n‐ZnO/a‐Al2O3 bipolar heterojunction diode.

“…The increase in Urbach energy also confirmed the increase in disorder and imperfection within the energy bands of ZnS:Cu doped PVA nanocomposite films . Sheha et al prepared PVA‐CuI nanocomposite polymer electrolyte for application in photovoltaic cells and also investigated the structural, optical and dielectric properties of the polymer nanocomposite electrolyte. In the same vein, report on the morphological and thermal properties of PVA nanocomposite containing CdS and ZnS have been documented in literature .…”

Effect of SrO nanofillers on the physical and chemical properties of newly prepared PVA nanocomposites was investigated in‐depth in this article. The structure of SrO nanopowder and PVA nanocomposites were analyzed using FTIR for surface chemistry and XRD for crystallographic nature. The extent of dispersion and particle size of SrO nanopowders were obtained from TEM micrographs. The average particle size of the SrO nanopowder was 57 nm. The uniformly dispersed SrO nanofillers in the host PVA matrix were observed from the TEM micrographs. The prepared PVA nanocomposites displayed a high absorption in the UV region. The thermal stability of PVA nanocomposites was enhanced after the addition of SrO nanofillers. The nonisothermal degradation study was carried out using different kinetic models for the prepared PVA nanocomposites. The Young's modulus (Y) and tensile strength of the PVA nanocomposites were higher than that of the pristine PVA. The DC conductivity of PVA was also increased when the PVA was embedded with the SrO nanoparticles. Highlights The novel PVA nanocomposites embedded with SrO nanofillers were prepared by the solution casting method. The band gap of PVA was decreased gradually while increasing the concentration of SrO nanofillers. The thermal degradation of polymer composites was studied under nonisothermal heating using several kinetic models. The thermal stability of PVA was enhanced after the addition of SrO nanofillers. The electrical and mechanical Properties of PVA nanocomposites were also improved.

“…Additionally, PVA possesses a carbon backbone that contains hydroxyl group attached, and that can be a source of hydrogen bonding which enables the formation of polymer nanocomposites [17]. Many conventional methods have been reportedly used to evaluate the spectra, morphological and thermal characterization of polymer nanocomposites.…”
