Scientists from Argonne National Laboratory and various universities have made a significant breakthrough in X-ray technology by successfully analyzing a single atom. This achievement has far-reaching implications for fields such as quantum technology, medical research, and the development of new technologies.
Traditionally, X-ray analysis has been limited to samples containing about 10,000 atoms. However, the multi-institutional team has now pushed the boundaries by scaling down their observations to a single atom. This breakthrough opens up new possibilities in various scientific disciplines and technological advancements.
By utilizing X-ray beams, the researchers were able to characterize the elemental type and chemical properties of a single atom. This capability provides a unique fingerprint for the elements present in a material, enabling precise identification. The potential applications of this advancement range from quantum information technology to environmental and medical research.
To achieve this feat, the scientists isolated a single iron atom within a nanometer-scale molecule composed of different elements. They then utilized the Advanced Photon Source (APS) at Argonne’s light source, along with a scanning tunneling microscopy (STM) probe, to detect and study the single atom. The APS is one of the most powerful X-ray facilities in the world.
The X-ray beams cause the sample to release electrons when bombarded, which are then collected by the STM probe positioned near the sample surface. The resulting spectra, representing plots of current versus photon energy, act as unique fingerprints for each element. This allows scientists to identify the type and location of the atom with precision.
Furthermore, the researchers can determine the chemical state of the atom based on the same spectrum. The chemical state is crucial for understanding the physical, chemical, and electronic properties of the atom. By expanding this technique to rare earth elements like terbium, which are vital in various industries, the team demonstrated the broader applicability of their approach.
This groundbreaking achievement in X-ray analysis of single atoms signifies a transformative milestone in scientific research. The newfound ability to study atoms individually opens up unprecedented opportunities for technological advancements and scientific discoveries. Funding for this research was provided by the U.S. Department of Energy’s Office of Basic Energy Sciences, and computing resources were made available by the Laboratory Computing Resource Center at Argonne.
