Abstract

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.
