- Аннотация: The spectrum was obtained and the time dependences of the fractoluminescence signals were studied during the destruction of the quartz surface bymicrocutting perpendicular to the (0001) axis. An analysis of the obtained data showed that clusters of the 4 smallest ”primary“ cracks appear during fracture. The formation of cracks is associated with the destruction of barriers that prevent the movement of dislocations along slip planes. The crack sizes are several nm, and the growth rate is several m/s. The size distribution of cracks has a power law form.
