 o 일시 : 2023.02.28. 11:00 ~ 
 o 장소 : E6-2 #1322호
 o 강연자 : 김우진 박사(Stanford Institute for Materials and Energy Sciences, SLAC National Accelerator Laboratory)
 o 주제 : "Topotactic redox engineering toward novel material "
 
 o Abstract
Due to their multiple oxidation states, transition metal oxides can be existing in various forms with different structure symmetries. By selectively introducing or removing oxygen from specific sites in a crystal lattice, it is possible to manipulate the material's electronic structure, leading to the emergence of quantum phenomena, such as colossal magnetoresistance and superconductivity [1,2]. Topotactic redox reactions allow for this reversible reduction and oxidation process to occur without altering the relative structure of the cations of the material. In this talk, I will discuss a quasi-two-dimensional material system that is stabilized through topotactic reduction, where the Jahn-Teller effect results in a beautiful pattern of distortions. In the second half of the talk, I will introduce the use of mechanochemistry on freestanding oxide membranes to greatly reduce activation energy for redox reactions, which can be useful for creating new and clean functional oxides.
