title: Simultaneous in-situ synthesis and characterization of Co@Cu core-shell nanoparticle arrays.
abstract: Core-shell particle ensembles are fabricated by pulsed-laser-induced dewetting of initially continuous, ultrathin alloy films through a combination of morphological and chemical instability. The synthesis of these arrays is monitored in situ with high spatial and temporal resolutions, which, when combined with ex situ composition analysis, provides insight to the morphological and chemical evolution pathways leading to core-shell particle formation.
