“…In addition, the I – V curve is linear showing the low-resistance ohmic contacts of CdS NRs with the Ag electrode. This is the most important property of CdS NRs in comparison with other semiconductors. − The flexible durability of the coatings according to the number of folding cycles was performed by measuring the variation of sheet resistance, as shown in Figure c. The electrode showed the best durability in that the variation ( R – R 0 )/ R 0 of sheet resistance was small after completion of the folding test (500 cycles).…”

A simple pathway for the fabrication of real moth eyelike patterned (MEP) polymer film with a double-layered nano/microhierarchical structure is demonstrated through a solid/liquid interfacial reaction at atmospheric conditions. A convex-structured polyvinyl alcohol (PVA) film containing CdCl 2 was first fabricated using a self-organized honeycomb-patterned porous film as a template. The CdCl 2 /PVA convex film was immersed into Na 2 S/ethanol solution to facilitate the reaction between CdCl 2 and Na 2 S at the solid/liquid interface, which led to the functionalization of CdS nanoparticles in the convex-structured PVA film. The tunable introduction of interfacial reaction resulted in the formation of a CdS moth eyelike nanoarray on the top surface of the PVA convex microarray, which mimicked the real moth eye (PVA−CdS MEP). PVA−CdS MEP film with a double moth eyelike structure showed improved antireflective property in comparison with flat and convex-structured PVA films. The PVA−CdS MEP film showed photoresponse under simulated solar light radiation and flexible duration after 500 cycles of folding.

“…One of the important requirements in the above electronic devices is formation of the ohmic contact between a conventional metal electrode and the CdS layer . Indium or silver as well as aluminum are normally used as materials that are able to form such a contact to CdS . These contacts are made by thermal vacuum evaporation or by deposition of specially prepared metal particles suspended in organic solvents and stabilized by surface‐active compounds.…”

A conductive pyrolytic carbon fiber (CF) has been found to serve as an alternative material to metal electrodes, since it forms an Ohmic contact to CdS crystals. The methods of preparation of polycrystalline layers and nanocrystalline arrays of CdS are described that allow formation of an ohmic or quasi-ohmic contact to CF. It is shown that the ohmic contact between the CF and polycrystalline CdS layer is stable for at least several months and its exploitation characteristics are not worse than the indium contact. Advantages of the CF electrode, such as thermostability to extremely high temperatures and low cost are discussed.CdS nanowire arrays grown on a carbon fiber.
