报告题目：Advanced transmission electron microscopy on two-dimensional materials
摘要：In this presentation, I will present the recent electron microscopy technologies such as in situ TEM, lose dose TEM and 4D STEM, and their applications in energy materials, 2D materials and others. Especially, I will clarify the ferroic ordering in 2D and their physical origin, and introduce how to control/manipulate the phase transition and the ferroelectricity as well as ferroelasticity in 2D and build novel devices. We applied a variety of in situ transmission electron microscopy techniques, specifically employing in situ mechanical manipulation, in situ mechanical testing, in situ electrical testing, in situ heating, and in situ electron beam control, to conduct comprehensive investigations of ferroic phase transitions and ferroic ordering in two-dimensional (2D) chalcogenides. The diverse phases observed in these ferroic 2D materials showcase unique mechanical, electrical, and other captivating physical properties. Through our study, we successfully established a direct correlation between atomic-scale structures and device-level performance, thereby enhancing our understanding and enabling practical applications of 2D functional materials.
