(author), Watanabe, Kenji (author), Castellanos-Gomez, Andres (author)In two-dimensional materials research, oxidation is usually considered as a common source for the degradation of electronic and optoelectronic devices or even device failure. However, in some cases a controlled oxidation can open the possibility to widely tune the band structure of 2D materials. In particular, we demonstrate the controlled...journal article 2020

Hsu, C. (author), Frisenda, Riccardo (author), Schmidt, Robert (author), Arora, Ashish (author), de Vasconcellos, Steffen Michaelis (author), Bratschitsch, Rudolf (author), van der Zant, H.S.J. (author), Castellanos-Gomez, Andres (author)An interesting aspect of 2D materials is the change of their electronic structure with the reduction of thickness. Molybdenum and tungsten-based transition metal dichalcogenides form an important family of 2D materials, whose members show a thickness-dependent bandgap and strong light–matter interaction. In this work, the experimental...journal article 2019
