Automated diffraction tomography (adt)

Definition

Automated diffraction tomography (ADT) is a powerful technique used to determine the three-dimensional structures of materials at the nanoscale by analyzing the diffraction patterns generated by electron beams. This method integrates advanced imaging and computational techniques to systematically collect and reconstruct electron diffraction data, making it particularly valuable in the study of nanomaterials where traditional methods may fall short. By automating the data acquisition process, ADT enhances efficiency and accuracy, allowing researchers to capture detailed structural information that can lead to a deeper understanding of material properties and behaviors.
