Stacking-Engineered Ultrafast Charge Separation in Type-I Silicane/Germanane van der Waals Heterostructures

Stacking engineering in van der Waals heterostructures offers a powerful route to modulating band alignment and carrier dynamics. Here, we present a theoretical investigation of SiH/GeH van der Waals heterostructures with different stacking configurations. Distinct stacking-dependent band alignments are identified, w...

Photoexcited Polaron Dynamics in Rutile TiO 2 from First-Principles On-the-Fly Surface Hopping

Photoinduced polaron dynamics challenges the classical path approximation (CPA), which prescribes nuclear motion on a single potential-energy surface (PES). To overcome this limitation, we use ΔSCF-based on-the-fly surface hopping involving both ground- and excited-state PESs to study photoexcited polaron dynamics...
