▲ Kim Min-kyung (left), Prof. Rho Jun-sukUsing optical diodes in electronic devices are beneficial; by means of light, data processing speed can be enhanced, energy loss is reduced, and miniaturization is possible. However, because of light’s diffraction and interference, technology that can control light is necessary. Kim Min-kyung (ME, Ph.D. Integrated) and Professor Rho Jun-suk (ME, CE) have developed an optical diode that gives one-way light flow using symmetry-breaking metamaterials. Originally, the flow of an optical diode’s light is symmetrical, but using metamaterials, the research tea

▲ Graphene based vertical form of superconductor paringWhen a thin layer of conductor is placed between superconductors, supercurrent with no resistance flows between them. Such phenomenon, as according to Jospehson superconductor effect, had been brought into manufacture by complicated process of rendering evaporation of superconductors on conductors through multiple stages of evaporation. In this research, superconductor pairing with strong coherence characteristic has been materialized by simply decaling NbSe2 superconducting material on single layer of graphene in nanoscale.Professor Lee H

The research team discovered that they could selectively control the property of semiconducting and metallicity according to the deposition temperature synthesizing MoTe2 by chemical vapor deposition. Furthermore, the researc

Graphene has gathered expectations as a new material that is perfect for electric devices. There was one problem. Graphene has no band gap which can control electric flow. Professor Cho Kil-won’s team (CE) composed graphene into a bernal-stacked multilayer, giving it a band gap to solve the problem. This was possible using a catalyst made by attaching a thin film of nickel onto the copper circuit board, controlling the number of layers. Prof. Cho said, “Band gap controlling is a source technology related to commercialization, and is expecting it to make great contributions in developing flexib
