Abstract
A method of dividing single crystals, particularly of plates of parts thereof, is proposed, which can comprise: pre-adjusting the crystallographic cleavage plane () relative to the cleavage device, setting a tensional intensity (K) by means of tensional fields (), determining an energy release rate G(α) in dependence from a possible deflection angle (α) from the cleavage plane () upon crack propagation, controlling the tensional fields () such that the crack further propagates in the single crystal, wherein G(0)≧2γ(0) and simultaneously at least one of the following conditions is satisfied:
