In-Situ Mechanical Testing of Nano-Component in TEM

In situ TEM electromechanical testing of nanowires and nanotubes.

The emergence of one-dimensional nanostructures as fundamental constituents of advanced materials and next-generation electronic and electromechanical devices has increased the need for their atomic-scale characterization. Given its spatial and temporal resolution, coupled with analytical capabilities, transmission electron microscopy (TEM) has been the technique of choice in performing atomic ...

Double-tilt in situ TEM holder with multiple electrical contacts and its application in MEMS-based mechanical testing of nanomaterials.

MEMS and other lab-on-a-chip systems are emerging as attractive alternatives to carry out experiments in situ the electron microscope. However, several electrical connections are usually required for operating these setups. Such connectivity is challenging inside the limited space of the TEM side-entry holder. Here, we design, implement and demonstrate a double-tilt TEM holder with capabilities...

The MIAMI* facility at the University of Huddersfield is one of a number of facilities worldwide that permit the ion irradiation of thin foils in-situ in a transmission electron microscope. MIAMI has been developed with a particular focus on enabling the in-situ implantation of helium and hydrogen into thin electron transparent foils, necessitating ion energies in the range 1 – 10 keV. In addit...

M. Legros, D.S. Gianola, and C. Motz about the surface (e.g., optical and SEM) but have some advantages with regard to temporal resolution over 3D probing technologies, which can require long acquisition times to enhance the signal quality. Figure 1 is a three-axis map of the main in situ tools used to investigate deformation mechanisms. The first two axes are the strain resolution and the leng...
