Coherent acoustic phonons in a coupled hexagonal boron nitride–graphite heterostructure

Coherent acoustic phonons in a coupled hexagonal boron nitride–graphite heterostructure

Femtosecond optically excited coherent acoustic phonon modes (CAPs) are investigated in a free-standing van der Waals heterostructure composed of a 20-nm transparent hexagonal boron nitride (hBN) and a 42-nm opaque graphite layer. Employing ultrafast electron diffraction, which allows for the indepe...
