Scanning Transmission Electron Microscopes
Scanning Transmission Electron Microscopes (STEM) are advanced electron microscopes that use a focused beam of electrons to scan a sample and create high-resolution images. STEMs are capable of producing images with atomic resolution, allowing scientists to study the structure and composition of materials at the atomic scale. STEMs work by scanning a focused beam of electrons across a thin sample, and detecting the electrons that pass through the sample. By analyzing the electrons that pass through the sample, STEMs can create images that reveal the atomic structure of the material. STEMs are used in a variety of fields, including materials science, nanotechnology, and biology, to study the properties of materials and biological samples at the atomic scale.
