Abstract

original image

Silver nanoplates with multiple twin planes parallel to their basal surfaces exhibit multiple steps of structural distortion and phase transformation under increasing external pressure in a diamond-anvil cell. The disappearance of local hexagonal close-packed lamellae and a transformation from face-centered cubic to face-centered tetragonal phase are observed.
