Washington, DC — Although its name may make many people think of flowers, the element germanium is part of a frequently studied group of elements, called IVa, which could have applications for next-generation computer architecture as well as implications for fundamental condensed matter physics. New research conducted by Xiao-Jia Chen, Viktor Struzhkin, and Ho-kwang (Dave) Mao from Geophysical Laboratory at Carnegie Institution for Science, along with collaborators from China, reveals details of the element’s transitions under pressure. Their results show extraordinary agreement with the predictions of modern condensed matter theory.
Washington, DC—The U.S. Patent & Trademark Office has issued a patent to the Carnegie Institution for a method of creating high quality diamond crystals larger than 10 carats.
