主講人簡介：
Dr. Yoshifumi Oshima is a professor of Japan Advanced Institute of Science and Technology (JAIST). He received his doctor degree from Tokyo Institute of Technology in 2006 in Material Science. His research interests are novel physical and chemical properties of atomic scaled materials. He developed a miniature scanning tunneling microscope (STM) which can be installed in ultra-high vacuum transmission electron microscopy (UHV-TEM) and proved that gold nanowires have quantized conductance and so on. Recently, he established microscopic nanomechanical measurement method to estimate very low surface Young’s modulus of gold nanocontacts and also estimate individual bond stiffness in a Pt atomic chain. He received the society award (Seto prize) of the Japanese Society of Microscopy in 2011. From 2023, he becomes director of nanomaterials and devices research area in JAIST.
報告內容：
As nanomaterials shrink in scale, interest in their properties grows. Extensive research has demonstrated that nanoscale materials differ from bulk materials. However, as the scale decreases, atomic structure becomes crucial in determining nanomaterials' physical properties. Understanding the relationship between atomic structure and nanomaterials' properties is essential. This report focuses on nanomechanics and presents advanced strategies and characterization principles for enhancing transmission electron microscopy (TEM). It explores the structure-property link in nanomaterials, strategies for improving elasticity through atomic intercalation, precise measurement of single-layer two-dimensional materials' width, and first-principles calculations to enhance their elastic modulus.
