Reversible engineering of spin–orbit splitting in monolayer MoS₂via laser irradiation under controlled gas atmospheres

Abstract

Monolayer transition metal dichalcogenides, manifesting strong spin-orbit coupling combined with broken inversion symmetry, lead to a coupling of spin and valley degrees of freedom. These unique features make them highly...

Charge and energy transfer dynamics in single colloidal quantum dots/monolayer MoS2 heterostructures

“…1,2 In the 0D-2D heterostructures, the 0D-QDs have broad tunability of the bandgaps, high absorption cross-sections, and high quantum yields; [3][4][5][6][7] the 2D-TMDs have high transport mobility, direct optical band gap, and reduced dielectric screening. [8][9][10][11] Therefore, the 0D-2D van der Waals heterostructures have shown great potential in various optoelectronic applications, such as field-effect transistors, infrared photodetectors, and memory devices. [12][13][14] Investigation of charge and energy transfer between 0D-QDs and 2D-TMDs plays an important role in the design and performance improvement of these 0D-2D optoelectronic devices.…”
