| Popis: | The in situ three-point bending of a single self-suspended Au nanowire is visualized by micro Laue diffraction. The nanowire deflection is inferred from the displacement of Laue spots and it is well described by finite element analysis taking into account geometric nonlinearities and the elastic constants of bulk Au. This article1 reports on the first successful combination of micro Laue (µLaue) diffraction with an atomic force microscope for in situ nanomechanical tests of individual nanostructures. In situ three-point bending on self-suspended gold nanowires was performed on the BM32 beamline at the ESRF using a specially designed atomic force microscope. During the bending process of the self-suspended wire, the evolution of µLaue diffraction patterns was monitored, allowing for extraction of the bending angle of the nanowire. This bending compares well with finite element analysis taking into account elastic constant bulk values and geometric nonlinearities. This novel experimental setup opens promising perspectives for studying mechanical properties at the nanoscale. |
