| Abstract: | The dependence of the step parameters on the surface of base-faceted sapphire ribbons on the angle of deviation of crystallographic
orientation has been measured. A model of step formation on the lateral ribbon surface is proposed. Hysteretic character of
the dependence of the lateral ribbon surface inclination on the meniscus angle at the triple point is shown. The shapes of
the lateral surfaces are calculated and the range of variation in the meniscus angle is determined. |
