This study addresses the variation in electrical properties a thickening Al-doped ZnO (AZO) film up to 348 nm and correlates this with its defect chemistry.
In this study, we investigate the stability and electronic properties of bulk, surface, interface structures between tin sulfide (SnS) zinc (ZnS) by using first-principles calculations high-throughput structure search methods. Our analysis reveals significant differences in these materials, with distinct bandgaps observed for SnS ZnS bulk surface configurations as well at their pristine interface. The SnS/ZnS exhibits a staggered (type-II) band alignment, which is favorable solar cell...
In order to know the threshold quantity of zinc interstitials that contributes an increase in carrier concentration Al-doped ZnO (AZO) films and their effect on overall microstructure optoelectronic properties these films, this work, Zn-rich-AZO thin are fabricated by adding excess (from a metallic target) during deposition RF magnetron sputtering then investigated using wide range experimental techniques. All found grow hexagonal wurtzite crystal structure with strong (002) orientation...
Hierarchical metal mesh structures are fabricated for use as transparent conductive electrodes in electrochromic devices with large-band transmittance switching. Electrochromic materials (WO3 and Ta:NiO) deposited by plasma sputtering on the characterized a custom-made electrochemical setup allowing in-situ photo-spectrometer measurement. Both films exhibit high transmittance, not only visible but also NIR spectrum. based WO3 cathode Ta:NiO anode combined hierarchical fabricated. The...
In this study, a qualitative relationship between the surface and bulk electronic states for Al-doped ZnO (AZO) thin films (thickness < 260 nm) is established. To end, AZO were deposited on soda lime glass substrates by varying substrate temperature (Ts) from 303 K to 673 in RF magnetron sputtering. All these are found have grown hexagonal wurtzite structure with strong (002) orientation of crystallites an average transmittance 84%–91% visible range. Room scanning tunneling...
A combinatorial approach of experiment and theory was used to investigate the defect induced bulk surface electrical properties SnS.
Real-time in situ spectroscopic ellipsometry and situ, angle-resolved x-ray photoelectron spectroscopy (AR-XPS) have been applied to establish the relationships between growth kinetics developing microstructure of ultrathin (<3 nm) oxide films grown on clean Al–1.12 at. % Mg alloy surfaces by thermal oxidation temperature range T=300–485 K. To this end, procedures for depth-resolved quantitative AR-XPS analysis ultrathin, multiple-element, and/or multiphase overgrowths binary were...
