Abstract :
Tensile tests on notched plates of single-crystalline silicon were carried out at high overloads. Cracks were forced to
propagate on {110} planes in a < 1 1\ 0 > direction. The dynamics of the fracture process was measured using the potential
drop technique and correlated with the fracture surface morphology. Crack propagation velocity did not exceed a terminal
velocity of vc = 3800 m/s. which corresponds to 83% of the Rayleigh wave velocity vr. Specimens fractured at low stresses
exhibited crystallographic cleavage whereas a transition from mirror-like smooth regions to rougher hackle zones was observed
in case of the specimens fractured at high stresses.
Inspection of the mirror zone at high magnification revealed a deviation of the {110} plane onto {111} crystallographic facets.
