Advanced Analytical Scanning Transmission Electron Microscopy (STEM), and Future Directions

There has been increasing demand for so-called ‘workhorse’-type transmission electron microscopes as the technologies and techniques in (scanning) transmission electron microscopy (S/TEM) have evolved. Researchers and engineers from diverse industries depend on the unparalleled spatial resolution of S/TEM imaging for key structural insight into novel nanomaterials and devices, spurring recent developments of more flexible, reliable instrumentation.

In this webinar, learn about the key features that have developed to facilitate accurate, atomic-scale S/TEM imaging for industrial applications. Guest speaker Dr. Patrick Phillips, Assistant TEM Product Manager at JEOL USA, will be exploring hardware and operational strategies to optimize image resolution, clarity, and insight from advanced S/TEM imaging techniques.

Attendees at the live webinar event will receive a bonus 10% discount off their next TEM project with Covalent (Terms and Conditions apply).

This Webinar Will Answer

  1. What advancements are incorporated in modern S/TEM instruments?
  2. What are the current capabilities of a conventional S/TEM outfitted with a cold field-emission gun?
  3. What new possibilities for analysis are possible with the current state-of-art S/TEM?
  4. How can non-aberration corrected S/TEM be used to investigate and optimize advanced materials and devices?
  5. How is the field of S/TEM expected to expand and advance in the coming years?

Aberration Correction Isn’t as Necessary as It Once Was

For decades, only aberration-corrected S/TEM instruments were able to achieve reliable atomic resolution; analysts came to infer that aberration-corrected microscopes – often costing upwards of a million dollars to purchase, let alone maintain – were practically a prerequisite for capturing images at atomic scale.

Today’s tools turn that preconception on its head. Enhancements to cold field-emission sources, large-area silicon drift detectors (SDDs) and increased stabilization in the electron optics of transmission electron microscopes help to ensure top-quality images even in the absence of aberration correction. Find out how these recent technologies coalesce with operational strategies to enable new kinds of analysis on advanced materials and devices.
