Exploring Gold Contacts on Novel Carbyne-enriched Material

Gold contacts were deposited on a carbyne-enriched film, and the resistance between two electrodes and the sheet resistance of the carbyne-enriched film were measured before and after annealing at different temperatures, to explore the applicability of the gold as an electrode and the possibility for lowering the contact resistance. Resistances were measured and their relative changes were determined to qualitatively deduce the extent to which the annealing affects the contact resistance between the gold and the carbyne-enriched material. Exploring contacts between different metals and the carbyne-enriched film is of importance for the fabrication of future carbyne-based devices, for example, organic sensors detecting a variety of molecules such as harmful gasses.
