Learn how electron microscopy innovations can be used to understand the electric, magnetic, and microstructural crystalline properties at the nanoscale as well as morphology, topography, and atomic/elemental contrast.

Imaging Magnetic Materials and Nanoparticles

Can a scanning electron microscope (SEM) image magnetic material? This is a commonly asked question, and there are legitimate concerns about putting magnetic samples in an SEM (e.g., magnetic distortion, damage to the final lens).

In this webinar, we will answer these questions in detail and introduce the advantages of the ZEISS Gemini column for imaging such materials. Through examples of several applications, we will highlight the optimal conditions and methods for imaging and performing analytics such as EDS and EBSD on demagnetized and magnetic samples and nanoparticles that will enable you to get the most out of your SEM. Finally, we will discuss a special contrast mechanism that enables imaging of magnetic domains using Type I magnetic contrast.

Key Learning Objectives

  • Understand the differences between immersion and field-free objectives and their influences in imaging magnetic materials.
  • Learn the optimal SEM conditions for imaging magnetized and demagnetized samples and nanoparticles at high resolution.
  • Investigate magnetic contrast using low-voltage SEM imaging.

STEM Imaging and Tomography in a SEM

Transmission electron microscopy (TEM) is an imaging technique that provides atomic-level imaging and is typically reserved for TEM dedicated instruments. In this discussion, we will outline the contrast mechanisms in transmission imaging and highlight how STEM in FESEMs is becoming an increasingly adopted technique for a wide variety of applications ranging from imaging nanomaterials, thin sections of biological specimens, and diffraction studies and crystal orientation mapping at the nanoscale. The final part of this session will focus on 3D tomography enabled with a new STEM holder that allows the sample to be tilted and how digital image correlation techniques and 3D reconstruction can provide 3D volume imaging at the nanoscale.

Key Learning Objectives

  • Learn about transmission imaging signal contrasts in a FESEM.
  • Become familiar with tilt tomography in FESEM.

Low-kV Scanning Electron Microscopy - Beyond Sample Topography

In recent years, advances in low-kV SEM imaging have resulted in new capabilities and applications. Improvements in spatial resolution supplement the advantages of low kV imaging, which include the ability to see surface information from both topography and material contrast perspectives, image nonconductive, and beam sensitive materials. In this discussion, Dr. Iwona Jóźwik will describe and explain the principles of low kV imaging and highlight various contrast mechanisms to study III–V semiconductors and electronic materials. The strong contrast mechanisms observed with the Gemini column provide the clear ability to distinguish dopant types (p or n type) and density variations in III–V semiconductor devices and quantum wells. Insights into identifying and understanding artifacts and damage from different sample preparation methods will also be presented.

Key Learning Objectives
  • Understand the advantages of low kV SEM for surface sensitive imaging.
  • Learn about contrast mechanisms with SE and BSE signals at low kV to differentiate various materials in heterostructures and study the dopant type and distribution.
  • Identify artifacts and damage from various sample preparation methods.
