Positional disorder of Ba in the thermoelectric germanium clathrate Ba6Ge25
V. Petkov, T. Vogt
The local structure of Ba6Ge25 has been studied by x-ray diffraction and the atomic pair distribution function technique at 40 K and room temperature. Unambiguous evidence has been…
Temperature dependent total scattering structural study of CaCu3Ti4O12
E. S. Bozin, V. Petkov, P. W. Barnes +4
X-ray and neutron powder diffraction data as a function of temperature are analyzed for the colossal dielectric constant material CaCu3Ti4O12. The local structure is studied using…
Chemical short range order obtained from the atomic pair distribution function
Th. Proffen, V. Petkov, S. J. L. Billinge +1
Many crystalline materials show chemical short range order and relaxation of neighboring atoms. Local structural information can be obtained by analyzing the atomic pair distributi…
High real-space resolution measurement of the local structure of Ga_1-xIn_xAs using x-ray diffraction
V. Petkov, I-K. Jeong, J. S. Chung +3
High real-space resolution atomic pair distribution functions (PDF)s from the alloy series Ga_1-xIn_xAs have been obtained using high-energy x-ray diffraction. The first peak in th…
