Atomic size effect in impurity indued grain boundary embrittlement

W. T. Geng, A. J. Freeman, G. B. Olson

Bismuth segregated to the grain boundary in Cu is known to promote brittle fracture of this material. Recently, Schweinfest et al. reported first-principles quantum mechanical calc…

Pressure effects on the electronic properties and superconductivity in the $β$ -pyrochlore oxides: $A$ Os $_{2}$ O $_{6}$ ( $A$ = Na, K, Rb, Cs)

R. Saniz, A. J. Freeman

We present a first-principles study of the electronic structure and superconducting parameters of the compounds $A$ Os $_{2}$ O $_{6}$ ( $A$ = Na, K, Rb, and Cs) and at ambient and applied…
