Dhiren Pradhan is a postdoctoral associate working with Ronald Cohen. His works involve experiments on ferroelectrics, piezoelectrics, hyperferroelectrics and magnetoelectric materials. He recently completed his Ph.D. in Chemical Physics from the University of Puerto Rico,USA.
Washington, DC—It would be difficult to overestimate the importance of silicon when it comes to computing, solar energy, and other technological applications. (Not to mention the fact that it makes up an awful lot of the Earth’s crust.) Yet there is still so much to learn about how to harness the capabilities of element number 14.
The most-common form of silicon crystallizes in the same structure as diamond. But other forms can be created using different processing techniques. New work led by the Geophysical Laboratory's Tim Strobel and published in Physical Review Letters shows that one form of silicon, called Si-III (or sometimes BC8), which is synthesized using a high-pressure process, is what’s called a narrow band gap semiconductor.
Amol Karandikar is a postdoctoral associate working with Tim Strobel and Reinhard Boehler. Amol is working on material synthesis and phase stability of carbon/hydrogen rich compounds and light element transport in metals.
Juli-Anna Dolyniuk is a postdoctoral associate from the University of California, Davis. Juli-Anna is working with Tim Strobel on the development of new carbon and carbon-rich frameworks.
Washington, DC—Germanium may not be a household name like silicon, its group-mate on the periodic table, but it has great potential for use in next-generation electronics and energy technology.
Of particular interest are forms of germanium that can be synthesized in the lab under extreme pressure conditions. However, one of the most-promising forms of germanium for practical applications, called ST12, has only been created in tiny sample sizes—too small to definitively confirm its properties.
The AGU Fall Meeting 2016 will take place in San Francisco, CA from December 12-17. Many staff members and postdoctoral associates from the Geophysical Laboratory will attend this year.
