- Materials Science & Engineering

Over the last 100 years, materials scientists have made tremendous advances in developing revolutionary materials that shape everyday life. High purity semiconductors, glass fibers, polymers, bio-materials, structural steels, carbon fiber composites are but a few examples of materials that fundamentally impact human life. The field of Materials Science and Engineering is currently evolving at a more rapid pace than at any point in history, creating new technological opportunities by overcoming limitations with suitable new solid materials and hence impacting a broad range of modern sciences and technologies.

The Department of MSE at POSTECH is consistently recognized as a world-class research institution, based on its advanced academic program, its world-recognized faculty, and the high caliber of its students. Materials scientists and engineers at POSTECH are pursuing a new paradigm that will take our discipline in exciting directions: nano electronics and photonics materials and systems, advanced structural materials, energy and environmental materials, bio and polymeric materials, and fundamental/computational materials science. This new landscape offers tremendous opportunities and challenges, and POSTECH’s MSE department is extremely well positioned to remain at the forefront of this materials revolution.

(1) Nano Electronic Materials and Systems

The field of nano-scale electronic materials and systems is a perse and rapidly-evolving area in MSE. A wide variety of unique electronic and mechanical properties have been discovered for materials with nanoscopic dimensions, leading to breakthrough technologies and new functionalities in the field of electronics.
POSTECH’s MSE department excels in the areas of inorganic and organic nanowires, carbon nano tubes and graphenes, nano biosensors, high resolution lithography, and sub-nano-scale characterization.

(2) Nano Photonics Materials and Systems

Nano photonics, born out of the combination of three major sciences, nanotechnology, and optoelectronics, is one of the most important technologies for realizing global sustainability in the 21st century.
Nano photonics can provide high bandwidth, high speed, high efficiency, and ultra-small optoelectronic components and devices which will revolutionize telecommunications, display devices, computation, sensing, and lighting.
The physics and application of nano-scale photonic structures are widely investigated in the department of MSE. In particular we are interested in nano-photonic structures which can enhance light-matter interaction by orders of magnitude, ultra-high efficiency light emitters (LEDs and lasers) and solar cells.

(3) Advanced Structural Materials

This area focuses on the relationships between the chemical and physical structure of materials and their structural properties and performance.
Fundamental and applied research in this field responds to an ever-increasing demand for improved or better-characterized materials which will lead to innovations in infrastructures in transportation, large-scale power plants, etc., in the near future.
POSTECH’s MSE department excels in the areas of light-weight materials, high temperature/high strength materials, advanced steel technologies, and process development and characterization.

(4) Energy and Environmental Materials

With the increased demand for fossil fuels and subsequent concerns on environmental issues such as climate change, research in energy and environmental technology is more important than ever.
This research involves both developing materials to make alternative energy sources more affordable and efficient as viable replacements for fossil fuels and developing materials that enable tremendous energy savings.
The MSE department at POSTECH has focused on fuel cells, organic photovoltaics, dye-sensitized solar cells, batteries, and highly efficient inorganic and organic light emitters.

(5) Bio and Polymeric Materials

The main research topics are biomedical nanomaterials for nano-biomedicine and organic electronic materials and devices, studied from the basis of an in-depth understanding of the fundamental concepts of bio, organic, and polymeric materials science and engineering.
Nano-biomedicine is the exploitation of advanced nano-biotechnology in biosensors, bio-imaging, drug delivery and tissue engineering. The research for organic electronic materials and devices focuses on next-generation flexible electronics and displays, organic semiconductor devices, organic light-emitting diodes, and organic solar cells.

(6) Fundamental/Computational Materials Science

In this field of research, both computational and analytical techniques based on theoretical models are used to study the properties of condensed matter and atomic/molecular systems, aiming to enhance the communication between experimental materials research and theoretical/computational works on both existing and new/advanced materials and their applications.
Major research directions include the development of new computational methods and theoretical modeling of mechanical/optical/electrical properties of materials, especially nanostructures and advanced structural materials for applications in bio, energy and electronics.
