Stacking enabled strong coupling of atomic motion to interlayer excitons in van der Waals heterojunction photodiodes

Fatemeh Barati, Trevor B. Arp, Shanshan Su +6

We reveal stacking-induced strong coupling between atomic motion and interlayer excitons through photocurrent measurements of WSe${}_2$/MoSe${}_2$ heterojunction photodiodes. Strong co…
