Abstract

Nanoindentation tests were performed directly on solid and hollow cuprous oxide (Cu₂O) nanocubes. The hardness and elastic modulus of solid Cu₂O nanocubes were measured and compared with the values of bulk Cu₂O. It is found that the hollow cube top wall acts as a membrane that bends under an indentation load. The Cu₂O nanocubes are more ductile rather than brittle. Deformation behavior and fracture mechanics are discussed in conjunction with the structure of the Cu₂O nanocube.
