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…
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…
