Revealing the Structure-Property Relationship in van der Waals Materials by Nanomechanical Resonator

Van der Waals materials exhibit a rich phase diagram driven by structural changes in both interlayer and intralayer arrangements. A notable example is the field of twistronics, where controlling interlayer stacking orders leads to novel electronic properties. Understanding the relationship between structural and material properties is essential for the development of atomically thin, flexible, and energy-efficient devices. In this talk, I will present our recent progress in studying phase transitions, particularly stacking order transition and magnetic phase transition in 2D materials using nanomechanical resonators. These resonators provide valuable insights into critical aspects of phase transitions, such as thermodynamic behavior. With a deeper understanding of phase transitions in 2D materials and their effects on optical and electrical properties will unlock new opportunities for the development of 2D-material-based devices.
