  • 1233 Phase-Field Study of Interface Energy Effects on Morphology of Self-Formation Quantum Dots

抄録

The most promissing approach for creating small and dense dots needed for device application is via the spontaneous self-assembly of islands which occurs during Stranski-Krasnatow (SK) growth. In SK growth, the island shape is determined by the competition among surface energy of thin film, surface energy of substrate, interface energy between thin film and substrate, and elastic strain energy due to lattice misfit. In this study, in order to investigate the effects of interface energy on the island shape and island growth kinetics, we construct Multi-Phase-Field method taking into account the deposition of thin film material.
