Hierarchically structured sub-bands in chalcopyrite thin-film solar cell devices

“…The resistivity of the prepared films depends on the crystalline nature of the films: pure CGST (0.080 Ohm cm) and V – 0.075 (0.129 Ohm cm); there is a decrease in resistance and an increase in the conductivity values for V-incorporated CGST thin films, owing to the less grain boundaries and lattice stain in the CGST crystal structure. 42 Vanadium incorporation introduces impurities and defects into the crystal lattice of CGST. These defects can create localized energy states within the band structure of the material and also affect its electronic and transport properties.…”

Cross-linked graphene oxide framework to enhance pervaporation separate property of waterborne polyurethane in food packaging materials

“…Compared with the G peak position of GO (1598 cm -1 ), GO-OPD (1578 cm -1 ), GO-PPD (1571 cm -1 ), and GO-EDA (1580 cm -1 ) move to a low wavenumber direction. From this, it may be deduced that the rGO has isolated double bonds, which resonated at a higher frequency than the G band of GO, but near the G band of graphite (1581 cm -1) (Viveka et al, 2022), which corresponds to the restoration of a defective hexagonal network of carbon atoms.…”
