Mechanical Exfoliation and Characterization of Single‐ and Few‐Layer Nanosheets of WSe2, TaS2, and TaSe2
Abstract
Single‐ and few‐layer transition‐metal dichalcogenide nanosheets, such as WSe 2, TaS 2, and TaSe 2, are prepared by mechanical exfoliation. A Raman microscope is employed to characterize the single‐layer (1L) to quinary‐layer (5L) WSe 2 nanosheets and WSe 2 single crystals with a laser excitation power ranging from 20 μW to 5.1 mW. Typical first‐order together with some second‐order and combinational Raman modes are observed. A new peak at around 308 cm−1 is observed in WSe 2 except for the 1L WSe 2, which might arise from interlayer interactions. Red shifting of the A1 g mode and the Raman peak around 308 cm−1 is observed from 1L to 5L WSe 2. Interestingly, hexagonal‐ and monoclinic‐structured WO 3 thin films are obtained during the local oxidation of thinner (1L–3L) and thicker (4L and 5L) WSe 2 nanosheets, while laser‐burned holes are found during the local oxidation of the WSe 2 single crystal. In addition, the characterization of TaS 2 and TaSe 2 thin layers is also conducted.

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.
