114學年上學期 第二週 專題研討課程 演講公告 (114年9月15日)
題目:
Visualizing Atomic Vibrations: A New Frontier in Electron Microscopy
演講者: Xiaoqing Pan 特聘教授
現職: 加利福尼亞大學 材料科學與工程及天文物理系 特聘教授
時間: 114年9月15日(一) 15:20~17:10
地點: 成功大學成功校區 三系館 A1307
內容摘要:
Recent groundbreaking developments in aberration-corrected scanning transmission electron microscopy (STEM) combined with advanced vibrational electron energy-loss spectroscopy (EELS) techniques have fundamentally transformed the way atomic-scale lattice dynamics and phonon behaviors are studied. In this seminar, I will highlight our seminal work in developing and applying state-of-the-art, spatially and momentum-resolved vibrational EELS methodologies to directly visualize phonon modes at atomic resolution. Our approach enables the unprecedented observation of localized phonon phenomena at individual defects, interfaces, and nanostructures, profoundly advancing our understanding of phonon-defect interactions, thermal boundary conductance, and electron–phonon coupling in materials.
