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.
