The “breathing”, or the vibrational motion of materials, contains rich information about the physical and chemical properties and states. Raman spectroscopy is a powerful analytical tool to see such “breathing”. In this talk, I will present some examples on how we can “see breathing” of 2D materials systems, including twisted bilayer MoS2 and few-layer black phosphorus, and how the “breathing” behaviors of coupled nanomaterials are influenced by each other which leads to new opportunities in chemical and biological sensing.
