Surface Cu components based on Cu LMM deconvolution.
Samples | Kinetic energies (eV) | Peak area ratiosa, Cu+ : Cu0 | |
---|---|---|---|
Cu+ | Cu0 | ||
Reacted Cu/Si | 916 | 918.7 | 6.8 : 1 |
Reacted Cu2O/Si | 915.6 | 918.6 | 14.7 : 1 |
Reacted CuO/Si | 915.6 | 918.5 | 4.8 : 1 |
Peak area ratios of Cu+ to Cu0 were calculated by the deconvolution of Cu LMM XAES.
