A Wide Optical-Gap in Fully -Like Hydrogenated Monolayer Graphene
Alice Apponi, Orlando Castellano, Daniele Paoloni +5
A comprehensive spectroscopic characterisation of two highly hydrogenated monolayer graphene samples transferred onto nickel grids is reported. With X ray photoemission spectroscop…
Influence of sulphur vacancies on ultrafast charge separation in WS-graphene heterostructures
Johannes Gradl, Niklas Hofmann, Leonard Weigl +6
Understanding how defects influence charge separation in WS-graphene heterostructures is crucial for future applications in light harvesting and detection. Previous studies hav…
Stability of Highly Hydrogenated Monolayer Graphene in Ultra-High Vacuum and in Air
Alice Apponi, Orlando Castellano, Daniele Paoloni +20
The stability of hydrogenated monolayer graphene was investigated via X-ray photoemission spectroscopy (XPS) for two different environmental conditions: ultra-high vacuum (UHV) and…
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…
k-resolved ultrafast light-induced band renormalization in monolayer WS on graphene
Niklas Hofmann, Alexander Steinhoff, Razvan Krause +6
Understanding and controlling the electronic properties of two-dimensional materials is crucial for their potential applications in nano- and optoelectronics. Monolayer transition…
Non-equilibrium carrier dynamics and band structure of graphene on 2D tin
Maria-Elisabeth Federl, Niklas Witt, Biao Yang +9
Intercalation of epitaxial graphene on SiC(0001) with Sn results in a well-ordered Sn structure on the SiC surface with quasi-freestanding graphene on top. While the e…
