Abstract:
This research is aimed at the development of an in situ tensile device which is suitable for standard double-tilt electrical TEM holders. The device contains a hexagonal electrostatic chip with a diameter of 1.8 mm. The chip has 706 pairs of combs, which provides an effective tensile displacement larger than 1 µm. To demonstrate the device performance, in situ tensile testing for penta-twinned silver nanowire is conducted in a high-resolution TEM. Experimental results show that the device can fulfill a tilt angle of 10° around both X and Y axes when performing in situ tensile testing experiments. The implemented tensile device has potential applications to characterize the deformation behavior of individual nanostructure in situ TEM at atomic lattice resolution level.
