XPS and XAES studies of surface segregation and oxidation of Cu-Ge alloy

Surface segregation of Ge is seen in the Cu-5at%Ge alloy with an activation enthalpy equal to 17 kJ/mol. Oxidation of the alloy in the temperature range 400 to 600 K shows the formation of Cu 2O and GeO which on further heating in vacuum at 650 K converts to GeO 2 with the reduction of Cu 2O to Cu.
