[交流] Nanoinstabilities as revealed by shrinkage of nanocavity

While the thermodynamic nonequilibrium properties of nanoparticles are being extensively studied, the thermodynamic nonequilibrium properties of their counterpart: nanocavities, however, are less noticed. Here, we systematically review and comprehensively model the recently published
results on the newly-found thermodynamic nonequilibrium properties of
nanocavities in covalently bound materials during energetic beam irradiation.
We also review and model the thermodynamic nonequilibrium properties of
nanoparticles. The review and modelling not only demonstrates the novel
nonequilibrium properties of such an open-volume nanostructure during
external excitation but also gives a deep insight into the nonequilibrium
thermodynamics of amorphous structures and the difference in the behaviours of defects in crystalline and in amorphous silicon. Especially, the review and modelling leads to two new concepts:
• anti-symmetry relation between a nanoparticle and a nanocavity
• energetic beam induced-soft mode and lattice instability in condensed
matter

which reveals that structure of a condensed matter would be unstable not only at nanosize scale but also at a nanotime scale in general. It is also reveals that such nanoinstabilities would be more pronounced in an amorphous structure
than in a crystalline structure.
