Exciton multipolarity controls coherent and squeezed phonons in van der Waals heterostructures
Photoexcitation-driven changes in the electronic distribution displace atoms, generating coherent phonons on ultrafast timescales.
Photoexcitation-driven changes in the electronic distribution displace atoms, generating coherent phonons on ultrafast timescales. Two-dimensional (2D) materials and their heterostructures offer a powerful platform for engineering these phonons. Yet, despite the widespread…
