Results and discussion Figure 2 shows the SEM images of the AZO/Ag/AZO structure irradiated with a single laser pulse of 1.7 J/cm2. An irradiated region can be clearly observed in Figure 2a with no damage in the surroundings or cracking in the glass substrate. Figure 2b illustrates the well-defined cutting edges that leave the bare substrate uncovered with a flat and clean surface. It should be noted that both edges present modulated profiles such as the ones obtained if a

laceration occurred. This quite large rip Brigatinib (approximately 200 μm wide) ensures an excellent isolation between the not irradiated DMD structure and the central area of the laser spot (see Figure 2c). Such an isolation is further guaranteed by the trilayer lift off from the substrate at the line border, as evident from the cross-sectional SEM image reported in Figure 2d. Figure 2 SEM micrographs of the irradiated AZO/Ag/AZO electrode. The laser

irradiation PARP inhibitor is a single pulse, at a wavelength of 1,064 nm, duration of 12 ns and energy fluence of 1.7 J/cm2. The corresponding laser-irradiated spot size is 9.1 mm2. (a) Overview of the spot, (b) fracture of the multilayer structure at the periphery of the irradiated area, (c) central region and (d) AZO/Ag/AZO lift off from the substrate at the edge. The structural modification of the central area of the laser spot was confirmed by means of the RBS technique. Figure 3 compares the energy

spectra of He+ backscattered by AZO/Ag/AZO samples outside and inside the irradiated region of Figure 2a. Three peaks are well distinguished in the as-deposited DMD. The one centred at 1.7 MeV is relative to He+ backscattered from Ag atoms, while the two peaks at 1.56 4-Aminobutyrate aminotransferase and 1.51 MeV are due to backscattering from the Zn atoms in the top and bottom AZO layers, respectively. Such a well-defined multilayer structure, present in the as-deposited DMD, disappears after laser irradiation, showing that both Ag and Zn atoms are now located at the surface (Ag signal shifted towards higher energy). The smaller area of Ag and Zn peaks after laser irradiation also indicates that a partial removal of these materials has occurred, while the broader shape of the signals is related to the loss of the sharp multilayer structure. This will have a noticeable effect on the electrical properties, as discussed in the following. Figure 3 Energy spectra of He + backscattered by AZO/Ag/AZO samples outside and inside the irradiated area. A scheme of the RBS experimental setup is reported in the inset. Figure 4 shows the separation resistance measured between two points, at a distance of 1.2 mm from each other, inside and across the laser spot, on our thin AZO/Ag/AZO sample irradiated with various laser fluences.
