On page 2439 , F. Östlund et al. report on an interesting effect observed during the compression of sub‐micrometer silicon pillars; a critical diameter separates pillars that are observed to crack from pillars that exhibit metal‐like ductility. This observation allows for the development of a quantitative method for measuring the fracture toughness of such structures, which can be used to predict and explain small‐volume fracture behavior.
