MIT Develops New Method to Locate Atoms in Materials

MIT scientists have introduced a groundbreaking computational technique called Discrete Grid Imaging Technique (DIGIT) that allows optical microscopes to identify individual atoms in materials. This innovation offers a clearer understanding of atomic structures, enhancing research and technological development across various fields.
Optical microscopes have long faced limitations in viewing features smaller than half the wavelength of visible light. This challenge often kept individual atoms from being seen. However, recent advancements in super-resolution microscopy had already pushed boundaries, allowing scientists to view structures down to the scale of single molecules.
Now, DIGIT adds a new layer of capability. The method combines knowledge of a material’s atomic configuration with optical data, creating a sort of “seating chart” for atoms. Lead author Yuqin “Sophia” Duan explains the method allows researchers to identify exactly where each atom sits within the crystal structure. “It’s like knowing which seat at a concert each atom occupies,” she says.
This approach achieves a remarkable resolution of 0.178 angstroms. To put that in context, one angstrom equals one-tenth of a nanometer. This precision gives scientists invaluable insight into how materials behave at atomic scales.
Duan and her team applied this technique to diamond crystals to successfully pinpoint silicon atoms that had replaced carbon ones within the lattice structure. By using the known organization of the diamond’s atomic grid, they improved image clarity and identified individual atoms. This method can similarly be used in any material with a recognizable atomic layout, such as certain proteins.
The potential applications are vast. Scientists could use DIGIT for developing quantum devices, where placement precision is critical. Additionally, understanding atomic arrangements can lead to innovations in semiconductors and superconductors, materials essential for advancing electronic technologies.
Unlike electron microscopes, which require high energies and special conditions, optical microscopes operate safely on biological samples. Hence, DIGIT opens new research avenues not only in materials science but also in biological fields.
The team has made the DIGIT code accessible on GitHub for other researchers, promoting collaboration in uncovering finer details in various materials. As Duan puts it, “This takes optical microscopes into the realm of atomic scale.” Scientists now look forward to broader applications of this cutting-edge technology in materials and biology, setting the stage for exciting advancements.
