Journal ArticleDOI
Giant bandgap renormalization and excitonic effects in a monolayer transition metal dichalcogenide semiconductor
Miguel M. Ugeda,Aaron J. Bradley,Su-Fei Shi,Felipe H. da Jornada,Yi Zhang,Diana Y. Qiu,Wei Ruan,Sung-Kwan Mo,Zahid Hussain,Zhi-Xun Shen,Feng Wang,Steven G. Louie,Michael F. Crommie +12 more
TL;DR: The renormalized bandgap and large exciton binding observed here will have a profound impact on electronic and optoelectronic device technologies based on single-layer semiconducting TMDs.
Journal ArticleDOI
Observation of giant bandgap renormalization and excitonic effects in a monolayer transition metal dichalcogenide semiconductor
Miguel M. Ugeda,Aaron J. Bradley,Su-Fei Shi,Felipe H. da Jornada,Yi Zhang,Diana Y. Qiu,Sung-Kwan Mo,Zahid Hussain,Zhi-Xun Shen,Feng Wang,Steven G. Louie,Michael F. Crommie +11 more
TL;DR: In this paper, the single-particle electronic bandgap of single-layer metal dichalcogenides (TMDs) was determined using scanning tunneling spectroscopy (STS) and photoluminescence spectrograms (PL).
Journal ArticleDOI
Missing Atom as a Source of Carbon Magnetism
TL;DR: The results show the possibility of inducing a macroscopic ferrimagnetic state in multilayered graphene just by randomly removing single C atoms.
