Abstract :
We have used soft x-ray emission spectroscopy to study the impact of the CdCl2 activation treatment on the chemical structure of the CdTe/ZnO1-xSx interface. We find a pronounced chemical interaction, most prominently the interfacial intermixing of Cd and Zn. Furthermore, the formation of S-Cd bonds at the expense of S-Zn bonds can be observed.
