Perovskite Film with 100x Luminous Efficiency
Professor Hong Seok Lee (Department of Physics, Research Institute of Physics and Chemistry, Chonbuk National University) and his team have developed a technique for manufacturing perovskite film 100 times the luminous efficiency. The researchers produced a highly crystalline perovskite film by treating it with a solvent vapor of various polarities. They also developed a method to control the emission wavelength and efficiency by controlling the crystal size in the film according to the expo..

Semiconductor with Lower Resistance and 100x Performance
When applying two-dimensional (2D) transition metal dichalcogenides (TMDs) to conventional devices, high contact resistance between the TMDs and metal electrodes has always been a stumbling block. CBNU Professor TaeWan Kim (Department of Electrical Engineering and Smart Grid Research Center) and his team have developed a technique that overcomes this problem and performs 100 times better than the existing 2D material-based semiconductors. The researchers succeeded in fabricating a next-ge..

Professor Solves a 30 Year-long Math Problem
There are limitations in dealing with uncertainty especially in a computing environment that requires accurate answers. To solve this, mathematicians and computer scientists have applied rough set theory. Since when it was first described by Zdzisław I. Pawlak in 1982, rough set theory has been considered to be a good way to solve problems in various computer-related fields. The theory contributed to theories such fuzzy theory, data analysis, deep learning, neural network theory and decisio..

Solvent-Free Green Synthesis of PLA Block Copolymers
For the first time in the world, researchers discovered a mechanochemical synthesis method of polylactic acid (PLA) block copolymers without using chemical solvent. Solvent is the most commonly used in chemical synthesis and is the main cause of environmental pollution and accidents. After two years of constant effort, Chonbuk National University undergraduates, Gue Seon Lee and Bo Reum Moon (Department of Chemistry, and Research Institute of Physics and Chemistry) and CBNU alumni Haemin ..

Depositing Material That Saves Time and Cost
Titanium dioxide (TiO2) is an excellent photocatalyst capable of oxidizing substances by absorbing light. It is widely used as a coating material for semiconductors and solar cells, as well as disinfectants, deodorizers and antibacterial agents. In industry, chemical vapor deposition and vacuum plasma deposition, such as the sol-gel process, have been generally applied to make TiO2 thin films, but such methods require high vacuum. Recently, low-temperature vapor deposition has been attractin..
