Determining the 3D Atomic Coordinates and Crystal Defects in 2D Materials with Picometer Precision

Quantum Materials with Atomic Precision: Artificial Atoms in Solids: Ab Initio Design, Control, and Integration of Single Photon Emitters in Artificial Quantum Materials

“…A significant hurdle in these systems is the lack of clear signatures which identify the source of emission [29] . Combined with fluorescence imaging, atomic-resolution imaging such as scanning transmission electron microscopy [1,31] or scanning tunneling microscopy [32,33] will likely soon lift these ambiguities by providing atomic details of quantum emitters [34][35][36] .…”

Atomic electron tomography in three and four dimensions

“…Several novel techniques could be employed to further improve the capabilities of AET, such as ptychography, [79][80][81] atomic elemental mapping, [82][83] 4D-STEM, [84][85] dose-efficient STEM, 86 low-dose modality imaging schemes with either advanced direct electron detectors 87 or cryogen temperature environment, [88][89] and in situ atomic imaging microscopy. [90][91] On the algorithm and method side, new method, 92 new reconstruction algorithm 93 and machine learning could further extend the applicability of AET to 2D materials, heterostructures, thin films and other material systems. With a combination of novel imaging modes and advanced reconstruction algorithms, we anticipate AET will play a key part in solving many fundamental problems in materials science, nanoscience, condensed matter physics and chemistry.…”
