Individual Vanadium Dopants Form Deep In-Gap States in Monolayer WS2
Tianhui Zhu, Carlos A. Gonzalez, Shihao Tu +11
Point defects in atomically thin materials have a strong impact on physical properties and those that induce in-gap states are advantageous for quantum information science and engi…
The ultrafast onset of exciton formation in 2D semiconductors
Chiara Trovatello, Florian Katsch, Nicholas J. Borys +11
The equilibrium and non-equilibrium optical properties of single-layer transition metal dichalcogenides (TMDs) are determined by strongly bound excitons. Exciton relaxation dynamic…
Observation of Moiré Excitons in WSe2/WS2 Heterostructure Superlattices
Chenhao Jin, Emma C. Regan, Aiming Yan +10
Moiré superlattices provide a powerful tool to engineer novel quantum phenomena in two-dimensional (2D) heterostructures, where the interactions between the atomically thin layers…
Optically discriminating carrier-induced quasiparticle band gap and exciton energy renormalization in monolayer MoS2
Kaiyuan Yao, Aiming Yan, Salman Kahn +7
Optoelectronic excitations in monolayer MoS2 manifest from a hierarchy of electrically tunable, Coulombic free-carrier and excitonic many-body phenomena. Investigating the fundamen…
Dynamics of Symmetry-Breaking Stacking Boundaries in Bilayer MoS2
Aiming Yan, Chin Shen Ong, Diana Yuan Qiu +5
Crystal symmetry of two-dimensional (2D) materials plays an important role in their electronic and optical properties. Engineering symmetry in 2D materials has recently emerged as…
Why do Collapsed Carbon Nanotubes Twist?
Hamid Reza Barzegar, Aiming Yan, Sinisa Coh +7
We study the collapsing and subsequent spontaneous twisting of a carbon nanotube by in-situ transmission electron microscopy. A custom-sized nanotube is first created in the micros…
