Spin-Orbit-Coupling-Governed Optical Absorption in Bilayer MoS<sub>2</sub> via Strain, Twist, and Electric Field Engineering

Spin-Orbit-Coupling-Governed Optical Absorption in Bilayer MoS<sub>2</sub> via Strain, Twist, and Electric Field Engineering

This paper investigates strain-, twist-, and electric-field-tuned optical absorption in bilayer MoS<sub>2</sub>, emphasizing spin-orbit coupling (SOC). A continuum model reveals competing mechanisms: geometric perturbations (strain/twist) and Stark effects govern one-/two-photon absorpti...
