Fig. 2.. (a) SEM image of the CdZnTe surface after the irradiation with N = 20 pulses with energy E = 5 μJ (F_p = 0.64 J/cm²). The red arrow represents the laser polarization direction; (b) Zoomed view of the marked region in (a), clearly showing long cracks with nanometer width formed on the surface (see also inset); (c) 2D-FFT of the crater in (a), indicating that the cracks are formed along direction at angles multiples of π/3.
