Research from McMorran lab featured in Around-the-O
The UO Physics McMorran lab has created a technique, STEM holography, that sends electrons along two separate paths, one going through a sample and one not. This allows them to measure the delay between them to create a high-resolution image. It provides improved atomic resolution of a sample’s outer structure and unveils previously unseen interfaces between a sample and underlying material.
UO researchers have now shown — using microscopes at the UO, Lawrence Berkeley National Laboratory and Hitachi Ltd. Research and Development Group in Japan — that STEM holography works.
“Using flexible STEM holography, an offshoot we developed in collaboration with Toshiaki Tanigaki at Hitachi, we now can capture with more precision the interesting geometries of materials,” Yasin said, “Previously, the field of view of STEM holography was limited to maybe 30 nanometers. Using flexible STEM holography expands the field of view.”
