Fabrication of Hexagonal Diamond by Aqueous Solution-based Electrochemistry: Rajakumar Sidharada Devarapalli1; Daniel Choi1; 1Khalifa University
Fabrication of hexagonal diamonds using anodized aluminum oxide (AAO) nanoporous template is performed by two step electrodeposition process. Initially, cobalt nanowires are deposited in the nanocavities of AAO template by applying constant current (galvanostatic) across the electrodes. Both the deposition time and the current applied were varied to identify suitable cobalt nanowire deposition for the second stage of hexagonal diamond deposition. Crystallography of deposited cobalt nanowires is controlled by altering PH of the electrolyte. In the second stage hexagonal diamonds are deposited over the cobalt nanowires by applying constant voltage (potentiostatic). A homogeneous solution of Acetonitrile and Methanol in a 1:1 ratio is used as an electrolyte in the second stage of the diamond deposition process. The yield of hexagonal diamonds is increased by altering the crystal structure of the seed Cobalt nanowire to HCP. The reproducibility of diamonds is achieved by optimization of the deposition process.
