WebIllumination system. It takes the electrons from the gun and transfers them to the specimen giving either a broad beam or a focused beam. In the ray-diagram, the parts above the specimen belong to illumination system. The objective lens and stage. This combination is the heart of TEM. The TEM imaging system. WebHigh-resolution TEM (HRTEM) images of the Pd NPs (Fig. 2 e) shows the presence of lattice fringes with spacing 0.112 nm, 0.137 nm and 0.225 nm, which are consistent with (222), (220) and (111) crystallographic planes of Pd respectively. The crystalline structure of Pd NPs was further characterized by the selected area electron diffraction (SAED).

WebJan 15, 2024 · A better solution for TEM is, instead, to use very high energy that has a bigger mean free path for scattering, accompanied by a thin specimen, so most of the beam will transmit through the specimen without generating secondary electrons. Reducing the electron dose rate can also reduce the total charging effect. WebMar 24, 2024 · It's pretty simple to enter the BIOS to check your CPU temperature.
