Understanding the dynamics of atomic vibrations confined in quasi-zero dimen- sional systems is crucial from both a fundamental point-of-view and a technologi- cal perspective. Using ultrafast electron diffraction, we monitored the lattice dynamics of GaAs ...
Here, using ultrafast electron crystallography (UEC), we report the observation of rippling dynamics in suspended monolayer graphene, the prototypical and most-studied 2D material. The high scattering cross-section for electron/matter interaction, the atom ...
Understanding the ultrafast evolution of atomic and electronic rearrangements under nonequilibrium conditions in organic, inorganic and biological materials plays a fundamental role in deciphering the mechanism governing chemical and biological functions. ...
