Ligament coarsening in nanoporous gold: Insights from positron annihilation study

R. N. Viswanath, V. A. Chirayath, and R. Rajaraman et al.

Positron lifetime experiments, coupled with scanning electron microscopy studies, have been used to follow the coarsening of the ligaments of nanoporous Au (np-Au), prepared by electrochemical dealloying of Ag75Au25. Positron lifetime measurements in the as-prepared np-Au indicate two lifetime com ... [Appl. Phys. Lett. 102, 253101 (2013)] published Mon Jun 24, 2013.
