TEM Testing

01 · Questions

What this test can help examine

  • Nanoscale morphology and defects
  • Crystal structure and phase assessment
  • Selected-area diffraction and localized composition

02 · Specimens

Information to prepare

  • Powders, films, bulk materials or devices
  • The observation area must be electron transparent
  • Preparation depends on the target region

03 · Method

A route matched to the research question

Bright-field, dark-field, high-resolution imaging, diffraction and spectroscopy are selected according to the research goal and paired with suitable mechanical, ion or FIB preparation.

04 · Deliverables

What may be included

  • Images at agreed magnifications and regions
  • Diffraction or spectroscopy data when scoped
  • Test conditions and result notes

05 · FAQ

Frequently asked questions

What should be confirmed before TEM testing?

Provide the material type, specimen condition, question to be answered and any existing data. An engineer will confirm preparation, test conditions and deliverables.

How are turnaround time and specimen quantity determined?

Turnaround time and specimen quantity depend on specimen condition, test scope and analysis requirements, and are confirmed during technical review.
