We have identified a new defect at the intersection between grain boundaries and surfaces in Au using
atomic resolution transmission electron microscopy. At the junction line of 90
h110i tilt grain boundaries
of (110)-(001) orientation with the free surface, a small segment of the grain boundary, about 1 nm in
length, dissociates into a triangular region with a chevronlike stacking disorder and a distorted hcp
structure. The structure and stability of these defects are confirmed by atomistic simulations, and we point
out the relationship with the one-dimensional incommensurate structure of the grain boundary
