Title:
Absence of Ni on the outer surface of Sr doped La 2 NiO 4 single crystals
Authors:
Burriel, Mónica; Wilkins, Stuart; Hill, John P.; Muñoz-Márquez, Miguel A.; Brongersma, Hidde H.; Kilner, John A.; Ryan, Mary P.; Skinner, Stephen J.
Abstract:
A combination of surface sensitive techniques was used to determine the surface structure and chemistry of La2-xSrxNiO 4+δ. These measurements unequivocally showed that Ni is not present in the outermost atomic layer, suggesting that the accepted model with the B-site cations exposed to the environment is incorrect. © 2014 The Royal Society of Chemistry.
