MSE Supplies is a trusted partner globally in helping to enable innovations. We have supplied materials, equipment, and lab supplies to over 2000 research laboratories and companies worldwide. We are a U.S. based supplier helping the advancement of research in fields such as materials science, photovoltaics, energy storage, semiconductors, optical materials, biomedical research, and basic science research, to name a few.
In this article, we highlight recent research work using our products that have been presented in a peer reviewed journal.
Researchers at the National Institute of Standards and Technology published a paper on measuring and mapping domains and the resulting stress in barium titanate. They purchased the barium titanate (BaTiO3) from us here at MSE Supplies.
The research focuses on using a technique known as electron backscatter diffraction (EBSD) to produce a stress strain map of the barium titanate single crystal. The measuring of stress and strain in these materials has been accomplished before but never on the microscale.
|Fig. 1. Optical micrographs of isolated domains visible on the surface of a BaTiO3 single crystal with majority domain polar c axis oriented perpendicular to and out of the image plane. Surface topography arises from differential etching of different domain orientations. (a) Isolated lenticular a domains with polar axis oriented parallel to the image plane and 90° domain boundaries with the majority domain. (b) Isolated blocky c domains with polar axis oriented into the image plane and 180° domain boundaries with the majority domain.|
They found that high resolution ESBD can generate a special resolution of 30nm with strain and rotation resolutions to about 10-4. This technique separated sub micrometer domains and their rotations within domains allowing for 2D strain, rotation, and stress mapping.
