Phason-driven temperature-dependent transport in moiré graphene
Alex Boschi, Alejandro Ramos-Alonso, Vaidotas Mišeikis +9
The electronic and vibrational properties of 2D materials are dramatically altered by the formation of a moiré superlattice. The lowest-energy phonon modes of the superlattice are…
Influence of doping on non-equilibrium carrier dynamics in graphene
Leonard Weigl, Johannes Gradl, Peter Richter +5
Controlling doping is key to optimizing graphene for high-speed electronic and optoelectronic devices. However, its impact on non-equilibrium carrier lifetimes remains debated. Her…
Influence of excitation energy on microscopic quantum pathways for ultrafast charge transfer in van der Waals heterostructures
Niklas Hofmann, Johannes Gradl, Leonard Weigl +3
Efficient charge separation in van der Waals (vdW) heterostructures is crucial for optimizing light harvesting and detection applications. However, precise control over the microsc…
Rubidium intercalation in epitaxial monolayer graphene
Letizia Ferbel, Stefano Veronesi, Tevfik Onur Mentes +7
Alkali metal intercalation of graphene layers has been of particular interest due to potential applications in electronics, energy storage, and catalysis. Rubidium (Rb) is one of t…
