摘要
Experiments on the formation of hollow nanocrystals by way of Kirkendall porosity resulting from a vary large Kirkendall effect have been reported recently by Yin et al. (Science, Vol 304, 2004, p 711). In the present paper, there is a discussion of some theoretical aspects of this process using chemical diffusion theory in the formal absence of vacancies at equilibrium. A formal description of the observed nanoscale Kirkendall effect is given that accompanies this process. A set of Monte Carlo simulations of the process are performed to verify the theoretical findings.
