Thermal Expansion, Anharmonicity and Temperature‐Dependent Raman Spectra of Single‐ and Few‐Layer MoSe2 and WSe2
Abstract
We report the temperature‐dependent Raman spectra of single‐ and few‐layer MoSe 2 and WSe 2 in the range 77–700 K. We observed linear variation in the peak positions and widths of the bands arising from contributions of anharmonicity and thermal expansion. After characterization using atomic force microscopy and high‐resolution transmission electron microscopy, the temperature coefficients of the Raman modes were determined. Interestingly, the temperature coefficient of the A 22u mode is larger than that of the A 1g mode, the latter being much smaller than the corresponding temperature coefficients of the same mode in single‐layer MoS 2 and of the G band of graphene. The temperature coefficients of the two modes in single‐layer MoSe 2 are larger than those of the same modes in single‐layer WSe 2. We have estimated thermal expansion coefficients and temperature dependence of the vibrational frequencies of MoS 2 and MoSe 2 within a quasi‐harmonic approximation, with inputs from first‐principles calculations based on density functional theory. We show that the contrasting temperature dependence of the Raman‐active mode A 1g in MoS 2 and MoSe 2 arises essentially from the difference in their strain–phonon coupling.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
