Reporter
Dr. DuckYoung Kim is currently a staff scientist at the center for high pressure science and technology Advanced Research (HPSTAR). His major is a computational approach to discovery new materials especially at high pressure conditions or more broadly at extreme conditions. Dr. Kim got Ph.D in condensed matter physics in 2009 from Uppsala Univ. Sweden. He conducted post-doctoral research at the theory of condensed matter group, Cavendish laboratory, Univ. of Cambridge UK for 2009-2011, and becomes a post-doctoral fellow at geophysical laboratory, Carnegie institution for science since 2011 and promoted to be a research scientist since 2014 until he moved to China to join HPSTAR in 2016.
Dr. Kim received 2010 Ångströms premium from Uppsala university, 2012 Benzelius Prize from the royal society of science in Uppsala Sweden, 2013 Jamieson award from international association for the Advancement of High Pressure science and technology, and 2017 plan for High level foreign experts from Chinese government. Dr. Duck Young Kim published 61 peer reviewed research papers including 3 Nature, 1 Nat. Mater., 1 Nat. Geo., 2 Nat. Commun., 1 Nano Lett., 1 Sci. Adv., 1 Angew. Chem., 7 PNAS, and 4 Phys. Rev. Lett. (27 papers published at high profile journals >= Phys. Rev. Lett.).
Abstract
Iron is one of key elements of human being’s industry and the main component of our planet. In this introductory talk, I will brief my group’s study on iron and its compounds mostly in the respect of high-pressure geophysics. I will start my talk from recent discovery of nearly room-temperature ferromagnetic vdW materials (Fe4GeTe2) for spintronics applications, which shows enhanced critical temperature with increasing iron layers. Then, I will move to present our discovery of FeO2 and its hydrous form (FeO2H) exhibiting superionic transition with temperature at lower mantle conditions. Last, I will show our study on Earth’s inner core and conclude my talk.
