| Abstract: | The technique of Auger line shape analysis is applied to Zn3P2 single crystal. Zn3P2 is a semiconductor that has some potential as a material suitable for solar energy conversion. The measured line shapes are band-like and so are amenable to analysis and comparison with theory. The line shapes are recovered from the spectra by background subtraction followed by the Van Cittert deconvolution. This technique is first applied to the L3VV line of copper and the results checked against those already in the literature. The line shapes for Zn3P2 are compared with band structure calculations. In general, there is good agreement between the theory and our measured valence band structure. |
