HRSEM research. Diagram of high-resolution scanning electron microscopy (HRSEM). This technique extends scanning microscopy to the atomic scale and provides information on both surface and bulk atoms simultaneously. The transmitted electron signal reveals the bulk structure (lower right). The secondary electron signal reveals surface details (upper right). The material is strontium titanate. The new technique was tested with TEAM 1.0 (Transmission Electron Aberration-corrected Microscope) at NCEM (the National Center for Electron Microscopy), the Molecular Foundry, at Lawrence Berkeley National Laboratory, California, USA. Diagram published in 2015.
