Real space elemental analysis using negative muon capture

Abstract: The disordered relaxor ferroelectrics display exceptional dielectric properties including record braking piezoelectric coefficients. One of the unique properties of these systems is that they display a distinct skin effect where the surface displays different properties over the bulk. One possible explanation for this is due to a chemical inhomogeneity that results from diffusion or other surface related effects. To investigate this, we propose to use negative muon capture to investigate the relative concentration as a function of depth in the sample. The proposal will ultimately test the possibility of using this technique for investigating relative elemental and ionic concentrations in the material. Potentially, this technique could be used to test industrial samples without the need for destroying the material to apply XAFS or EDX techniques.
