Thermal Conductivity and Tunable Thermal Anisotropy of Magnetic CrSBr Monolayer

Key Points

• The study aims to investigate the thermal conductivity and anisotropic properties of monolayer CrSBr.
• Conducted first-principles calculations to assess thermal properties.
• Analyzed the effects of phonon velocities and lifetimes on thermal behavior.
• Examined how flake size impacts thermal anisotropy.
• Found considerable thermal anisotropy with a ratio of approximately 1.8.
• Determined that anisotropy can be tuned by controlling flake size.
• Identified suppression of long mean path phonons as a tuning mechanism.
