Experimental Measurement of Negative Grain-Boundary Triple Line Tension

We measured negative grain-boundary triple line tension within bulk hard-sphere colloidal polycrystals. Compared to the grain boundaries, the tension is predominantly distributed in the grain lattices. The negative tension drives finite premelting at triple junctions and leads to a marginally denser lattice nearby.
