This study provides experimental evidence of in\u2010plane ATC and ATEC in few\u2010layer ReS\n                    <jats:sub>2<\/jats:sub>\n                    , revealed through simultaneous two\u2010mode Raman thermometry.

As the layer thickness varies from 5 to 8L, the ATC and ATEC ratios monotonically increase from 1.29 and 1.52 to 1.36 and 1.94, respectively. The ab initio calculations reveal that the directional in\u2010plane anisotropy in phonon dispersion, group velocity, and Gr\u00fcneisen parameter gives rise to ATC and ATEC. This work paves the way for exploring in\u2010plane ATC and ATEC in other low\u2010symmetry 2D materials, with potential implications for device applications.\n
