Research Area

Our research Goal is to develop novel functional materials and device platforms leading to a revolutionary or disruptive innovation in technology. To fulfill this mission, our institute primarily focuses on fundamental research for the development of new functional materials that may revolutionize current technology in many areas including Information Technology (IT), Biotechnology (BT) and Energy & Environment Technology (EET). Our institute consists of four groups.

area

We encourage collaborative as well as individual research to promote synergy in advanced materials research. The experimental and theoretical results from “Emergent materials” group will provide insights to both self-assembly nano hybrid and soft materials groups for the synthesis of new multi-functional nanomaterials. Newly designed and synthesized self-assembled nanomaterials will be implemented into nanodevices by the “emerging device systems” group, for their potential electronic application

Emergent materials

Significant progress in materials science of the past decade is associated with the emerging paradigm of phase complexity and cross-coupling phenomena in functional complex materials, in which various degrees of freedom are intricately coupled and mutually interacting. Such mutual interactions couple the charge-spin-orbital-lattice and often induce multifunctional phenomena such as multiferroicity in which the magnetism and ferroelectricity coexist and are cross-coupled with each other. Balance between the tightropes of coupled physical degrees of freedom can lead to a plethora of enhanced physical responses to external stimuli, mesoscopic domain structures, or the mesoscopic coexistence of electronic/magnetically-distinct phases.

“Emergent Materials” research will focus on fundamental studies of the principles and properties of cross-coupled multi-functional materials. The main objectives in the emergent materials researches are

area1

- Scientific understanding of multi-functionalities based on mutual interactions of charge/spin/orbital/lattice

- Investigation of multifunctional phenomena induced in nanostructures

- Macroscopic and microscopic analyses for establishments of the theoretical backgrounds and principles of the multi-functionalities

The emergent materials research will be performed through tight collaborations among materials synthesis and macro-/micro-physical property investigations including spectroscopic investigation for electronic structure and magnetic properties and charge/spin/orbital/lattice structural determination and theoretical interpretations using first principles calculations and many-body model Hamiltonian approach.

The “Emergent materials” research group is composed of faculties from the department of physics (Prof. Jae-Hoon Park) and materials science and engineering (Prof. Hyun M. Jang), whose specialties are spectroscopic investigation of the basic properties of emergent materials and synthesis of multiferroic oxides, respectively. Prof. Stefan Kettemann from Germany is a condensed matter theoretical physicist with specialties in mesoscopic theories and critical phenomena.
