INVESTIGATION OF HEAT-TREATMENT EFFECTS ON NI C BILAYER PARAMETERS BYXRSW/

The influence of heat load on the parameters of a metal/carbon bilayer is studied in the case of a laser beam deposited Ni film (10-40 angst rom) sandwiched between carbon layers and subjected to annealing up to 300-degrees-C. Variation of Ni layer thickness and density has been o btained with the help of X-ray standing waves (XRSW) generated in Cr/C multilayer and a total external reflection fluorescence study. It has been observed that a heat treatment at 130-degrees-C gave a considera ble enhancement of the C layer thickness, which remained constant at f urther annealing, whereas the Ni layer thickness and density were prac tically stable up to 300-degrees-C.
