| Abstract Scope |
Quantitative 4D-STEM is moving from specialized acquisition toward routine, reproducible materials characterization as detector technology, optics control, and reconstruction algorithms advance together. By recording diffraction information at each probe position, 4D-STEM enables quantitative mapping of strain, phase, orientation, fields, and defects, not only in 2D but increasingly in 3D. This presentation will show how emerging integrated microscope workflows are improving quantitative reliability across experiments by linking scriptable scan optics to programmable detectors for synchronized multimodal acquisition. When acquisition parameters and detector responses are programmatically controlled, experiments can be repeated, optimized, and extended into autonomous routines that reduce operator bias and improve consistency. High-DQE detectors operating ten times faster than prior generations expand the parameter space for low-dose, in situ, and high-throughput experiments. These advances are especially important for multislice electron ptychography, where high-fidelity diffraction data can reveal unprecedented depth-resolved structure and fields in complex materials. |
