A comparative study of Cu-related Pasmonic effects in electrochemically nanostructured CuInSe2 and CuGaSe2 crystals
We study the differences in electrochemical nanostructuring of CuInSe2 and CuGaSe2 crystals. To make the crystals suitable for electrochemical nanostructuring, they are subjected to thermal treatment either in vacuum or in Zn vapors. It is shown that thermal treatment of CuInSe2 crystals in vacuum a...

| Sumario: | We study the differences in electrochemical nanostructuring of CuInSe2 and CuGaSe2 crystals. To make the crystals suitable for electrochemical nanostructuring, they are subjected to thermal treatment either in vacuum or in Zn vapors. It is shown that thermal treatment of CuInSe2 crystals in vacuum at 600–700oC is an appropriate procedure for the consequent electrochemical treatment, while treatment in Zn vapors at temperatures higher than 700oC is necessary to make CuGaSe2 crystals suitable for electrochemical nanostructuring. The possibility of luminescence enhancement via thin Cu film deposition onto nanostructured CuInSe2 and CuGaSe2 surfaces is explored. |
