The growth velocity of silicon <110> faceted dendrites as a function of the twin spacing was investigated by in situ observation. As the twin spacing increases, . <110> dendrite growth velocity nonlinearly decreases. The theoretical <110> and <112> dendrite growth velocities were calculated on the basis of the modified re-entrant corner model, and the theoretical growth velocity of <112> dendrites was found to be slower than that of <110> dendrites under the same twin spacing. The theoretical <110> dendrite growth velocity fits quite well with the experimental results.
