The interaction of nickel with a carbon surface at 20-280 degrees C

The thermal stability of the nickel-carbon system as well as the growth dynamics of nickel on carbon were investigated by AES. For temperatures higher than 120 degrees C, changes in the system, which can be ascribed to island formation are observed. Below 240 degrees C there is no indication of carbide formation. Changes in the Ni MNN peak are observed for temperatures higher than 240 degrees C but cannot be explained yet. For substrate temperatures of 20 and 120 degrees C a difference in the growth dynamics is observed when the film thickness exceeds 2.5 AA. The difference is explained by increasing island formation at high temperatures.
