WebJan 15, 2024 · First, the TEM column needs to be maintained at a high vacuum, at least 10 −5 Pa, to minimize undesired electron beam scattering and sample contamination. Secondly, specimens need to be thin enough for electrons to penetrate through, usually of the order of hundreds of nanometres for nanoscale imaging. WebHow TEM/STEM works — High energy electrons (80keV-300keV) are transmitted through electron transparent samples (~100nm thick) and measured. TEM and STEM have higher spatial resolution than SEM but require more complex and time consuming sample preparation methods. Collapse all Instrumentation Available FEI Tecnai T-12 Cryo TEM …
