Researchers have recently developed a unique microscopy technique to visualize the density of electric charge. The technique is based on the scanning and transmission of electrons. Materials with sub-angstrom resolution can be studied with the help of the new technique. The research, conducted at the University of California, Irvine, gives important clues related to electron distribution. The technique analyses atomic and molecular structures to get a broader idea about the distribution of electrons on them.
Understanding the Mechanism of Electron Charge Exchange
Several crystals exhibit ferroelectric properties, and the researchers at UCI studied the tendencies of these crystals. Electric polarization of crystals that can be reversed by the application of an electric field is called ferroelectricity. The researchers state that the new technique helped them in understanding the origins of ferroelectricity. Furthermore, they also studied the mechanism of charge transfer among various materials. The results from the research published in the Nature journal.
The new technique is an advancement in the domain of atomic studies. Researchers at UCI have made a huge leap from studying atomic structures to imaging electrons. The technique could help the research fraternity in studying the properties of various materials. Furthermore, it can also be deployed to engineer new materials with desired functionalities and properties. The development of well-defined materials is especially useful in development of data-storage devices. Other key areas of application for such materials are quantum computing and energy conversion.
Potential Improvements in Material Sciences
The new technique can help in easy generation of electron probes. Furthermore, the research offers a fresh perspective to study electron charge densities and other similar factors. One of the lead researchers pointed to the potential of this technique in revolutionizing materials sciences. Moreover, discovery and development of new types of materials could also be achieved with the new technique.
