Pohang University of Science and Technology or POSTECH is a private university located in Pohang, South Korea dedicated to research and education in science and technology.
In 2012 and 2013, the Times Higher Education ranked POSTECH 1st in its “100 Under 50 Young Universities” rankings.
Four research centers of the Institute for Basic Science (IBS), which were recently established by the Korean government to promote research in basic sciences, are located at POSTECH. Four scientists and their teams in the fields of mathematics, physics, chemistry and life sciences are currently carrying out research on campus.
Research Institutes and Infrastructure
Pohang Light Source (PLS-II)
The 3rd generation light source at POSTECH is the 5th in the world and the only synchrotron radiation accelerator in Korea. This national research facility, the heart of Korea’s cutting-edge science, enables studies on various structural characteristics of materials using light. The facility is utilized in various basic science to high-tech industrial research. Its performance improvement to PLS-II was successfully completed in 2012. Thousands of users visit yearly to conduct their research using PLS-ll.
4th Generation Light Source
The 4th generation light source (PAL-XFEL), which is currently under construction on the Pohang Accelerator Laboratory (PAL) premises and scheduled to be operational in 2015, is 10 billion times brighter than the 3rd generation light source. PAL-XFEL will generate new knowledge and discoveries in almost all technical and scientific disciplines including medicine, pharmaceutics, chemistry, material science, nanotechnology, power engineering and electronics.
Max Planck POSTECH/Korea Research Initiative
The Max Planck Society of Germany and POSTECH established two Max Planck Centers at POSTECH: the Max Planck-POSTECH Center for Attosecond Science and the Max Planck-POSTECH Center for Complex Phase Materials. This collaboration is not only a testament to POSTECH’s internationally renowned research excellence but, with the introduction of advanced research institute operation and management methods, also lays a foundation for the further strengthening Korea’s competitiveness in basic science research.
POSTECH Biotech Center
The POSTECH Biotech Center was founded in 2000 with the goal of becoming the hub of biotechnology research and business development (R&BD). The primary goal of the POSTECH Biotech Center is to incubate disruptive technologies in biotechnology areas for the development of immunology, pharmaceuticals, and nanobiotechnology. The Center has been participating actively in academia-industry collaboration both nationally and internationally.
National Institute for Nanomaterials Technology
The National Institute for Nanomaterials Technology, a core research center for advancement and commercialization of nanotechnology, is developing the next-generation semiconductor and display materials, etc. With its cutting-edge facilities, the Institute provides valuable technical support and assistance to industry, from research and development to commercialization. The Institute also supports and enables POSTECH researchers to actively carry out nanotechnology and other related areas.
C5 plays a pivotal role in catalyzing world-first convergence education and research, and fostering future global leaders with a creative and challenging spirit. C5 was named after Creative, Collaborative, Cultivating, Convergence, and Center. C5 has 7-stories with a size of 16,000 square meters per floor. The construction of C5 came at an investment of 31.5 billion won. Construction began in October 2013 and its inauguration ceremony was held on January 30, 2015.
The first three floors of C5 will be filled by the Department of Creative IT Engineering (CiTE) and the POSETCH Future IT Innovation Laboratory (i-Lab). CiTE and i-Lab use interdisciplinary-oriented education and innovative research. The remaining three floors will house POSTECH research teams that will work for POSTECH’s strategic promotion of research areas and subjects with huge growth potential. A modern open-space design allows various research teams to rearrange work areas freely to facilitate and promote dynamic collaboration.
The POSCO Pohang Center for Creative Economy will occupy the 5th floor of C5. The Center, led by POSCO, was established to maintain the competitiveness of the steel industry, promote source technology development, and nurture regionally-based “hidden champions” to vitalize venture businesses.

A Korean team of scientists tune BP’s band gap to form a superior conductor, allowing for the application to be mass produced for electronic and optoelectronics devices
The research team operating out of Pohang University of Science and Technology (POSTECH), affiliated with the Institute for Basic Science’s (IBS) Center for Artificial Low Dimensional Electronic Systems (CALDES), reported a tunable band gap in BP, effectively modifying the semiconducting material into a unique state of matter with anisotropic dispersion. This research outcome potentially allows for great flexibility in the design and optimization of electronic and optoelectronic devices like solar panels and telecommunication lasers.
To truly understand the significance of the team’s findings, it’s instrumental to understand the nature of two-dimensional (2-D) materials, and for that one must go back to 2010 when the world of 2-D materials was dominated by a simple thin sheet of carbon, a layered form of carbon atoms constructed to resemble honeycomb, called graphene. Graphene was globally heralded as a wonder-material thanks to the work of two British scientists who won the Nobel Prize for Physics for their research on it.
Graphene is extremely thin and has remarkable attributes. It is stronger than steel yet many times lighter, more conductive than copper and more flexible than rubber. All these properties combined make it a tremendous conductor of heat and electricity. A defect–free layer is also impermeable to all atoms and molecules. This amalgamation makes it a terrifically attractive material to apply to scientific developments in a wide variety of fields, such as electronics, aerospace and sports. For all its dazzling promise there is however a disadvantage; graphene has no band gap.
Stepping Stones to a Unique State
A material’s band gap is fundamental to determining its electrical conductivity. Imagine two river crossings, one with tightly-packed stepping-stones, and the other with large gaps between stones. The former is far easier to traverse because a jump between two tightly-packed stones requires less energy. A band gap is much the same; the smaller the gap the more efficiently the current can move across the material and the stronger the current.
Graphene has a band gap of zero in its natural state, however, and so acts like a conductor; the semiconductor potential can’t be realized because the conductivity can’t be shut off, even at low temperatures. This obviously dilutes its appeal as a semiconductor, as shutting off conductivity is a vital part of a semiconductor’s function.
Birth of a Revolution
Phosphorus is the fifteenth element in the periodic table and lends its name to an entire class of compounds. Indeed it could be considered an archetype of chemistry itself. Black phosphorus is the stable form of white phosphorus and gets its name from its distinctive color. Like graphene, BP is a semiconductor and also cheap to mass produce. The one big difference between the two is BP’s natural band gap, allowing the material to switch its electrical current on and off. The research team tested on few layers of BP called phosphorene which is an allotrope of phosphorus.
