Abstract.
This paper describes in detail quantitative studies of the spiral mode of crystal growth, particularly focussing on the critical dislocation distance between two spirals rotating in opposite direction using the model derived in (Cont. Mech. Thermodynamics 17, 373 (2006)) from the classical BCF model presented in (Philos. Trans. R. Soc. London Ser. A 243, 299 (1951)). Based on our numerical studies we can show that the critical dislocation distance is a function of the diffusion coefficient and the temperature coupling constant as well as a function of the desorption rate. However, it is not a function of the flux rate.
