This webinar provides a fundamental introduction to atom probe tomography (APT) and 3D nanoscale imaging mass spectrometry, with a focus on interpreting the resultant data. Further, we explore how APT can create more efficient energy-producing materials, and how the technique can be applied to new applications. An overview of applications in metals, semiconductors, and insulators, with examples of how atom probe tomography has been applied to solve real-world problems, is provided. This introduction to the technology and applications provides insight into how you can use APT in your research. Presented by CAMECA.
