Spin-dependent Tunneling Barriers in CoPc/VSe2 from Many-Body Interactions
Runrun Xu, Fengyuan Xuan, Su Ying Quek
Mixed-dimensional magnetic heterostructures are intriguing, newly available platforms to explore quantum physics and its applications. Using state-of-the-art many-body perturbation…
Isolated Flat Bands and Physics of Mixed Dimensions in a 2D Covalent Organic Framework
Juefan Wang, Su Ying Quek
We demonstrate that it is possible to rationally incorporate both an isolated flat band, and the physics of zero dimensions (0D), one dimension (1D), and two dimensions (2D) in a s…
Hydrogen adatoms on graphene: the role of hybridization and lattice distortion
Keian Noori, Su Ying Quek, Aleksandr Rodin
Hydrogen adatoms on graphene are investigated using DFT and analytical approaches. We demonstrate that the level of lattice deformation due to the hydrogen adsorption does not subs…
Near Unity Molecular Doping Efficiency in Monolayer MoS2
Milad Yarali, Yiren Zhong, Serrae N. Reed +11
Surface functionalization with organic electron donors (OEDs) is an effective doping strategy for two-dimensional (2D) materials, which can achieve doping levels beyond those possi…
Dielectric Screening by 2D Substrates
Keian Noori, Nicholas Lin Quan Cheng, Fengyuan Xuan +1
Two-dimensional (2D) materials are increasingly being used as active components in nanoscale devices. Many interesting properties of 2D materials stem from the reduced and highly n…
Valley Zeeman effect and Landau levels in Two-Dimensional Transition Metal Dichalcogenides
Fengyuan Xuan, Su Ying Quek
This paper presents a theoretical description of both the valley Zeeman effect (g-factors) and Landau levels in two-dimensional H-phase transition metal dichalcogenides (TMDs) usin…
