Professor Ahn Jong-hyun's team (Dr. Jang Ho Wook, Ph.D.) has developed a time-resolved SHG imaging system capable of analyzing the ultrafine motion of molybdenum disulfide (MoS2), a representative two-dimensional semiconductor material, at a resolution of 300 nanometers (IF: 19.791), and was selected as a cover paper in recognition of its excellence in research.
