Twist Angle Dependent Ultrafast Transient Dynamics of MoSe${}_2$/WSe${}_2$ van der Waals Heterostructures beyond the Exciton Mott Transition

Vikas Arora, Pramoda K Nayak, Victor S Muthu +1

Two-dimensional van der Waals heterostructures (HS) exhibit twist-angle ($\theta$) dependent interlayer charge transfer, driven by moiré potential that tunes the electronic band structu…
