30. Structural contribution to light-induced gap suppression in Ta2NiSe5

An excitonic insulator is a material that hosts an exotic ground state, where an energy gap opens due to spontaneous condensation of bound electron-hole pairs. Ta2NiSe5 is a promising candidate for this type of material, but the coexistence of a structural phase transition with the gap opening has led to a long-standing debate regarding the origin of the insulating gap. In this talk, I will...

29. Visualizing Energy Transfer and Phonons During Charge Transfer at 2D van der Waals Heterojunctions Using Ultrafast Electron Diffraction

Archana Raja (LBNL)

Van der Waals crystals enable the construction of arbitrary, atomically precise heterostructures through straightforward layering of different monolayers without requiring covalent bonds or epitaxial matching. Understanding charge and energy transfer mechanisms in these atomically thin, two-dimensional (2D) material interfaces is fundamental to their electronic and electrochemical...
