Abstract:

Local structural distortions in Indium Arsenide at 11 GPa are studied applying the Fourier-transform analysis to As K-edge XAFS restricted to a short exploitable energy range of ~ 250 eV above the edge, due to the Bragg reflections from the diamond anvils. The best model for the radial distribution of In-atoms around As is obtained by combining available XRD data with a fitting procedure of the XAFS data, where alternative models for As coordination have been tested. InAs at 0.4 GPa was used as reference compound to minimize the number of variable parameters.
