Summary of the Raman modes (E2g, A1g), their separation (∆k) and relative weightage of the PL peaks obtained through Gaussian deconvolution for 1L-MoS2 and 1L-MoS2/WS2 QD HS.
| Sample | Raman modes | Relative weightage of PL peaks | |||||
|---|---|---|---|---|---|---|---|
| E2g (cm−1) | A1g (cm−1) | ∆k (cm−1) | B-exciton (B) (%) | A-exciton (A) (%) | Trion (A−) (%) | Bound exciton (X) (%) | |
| 1L-MoS2 | 387.6 | 407.2 | 19.6 | 13.2 | 53.0 | 23.2 | 10.6 |
| 1L-MoS2/WS2 QD | 387.6 | 406.0 | 18.4 | 15.5 | 20.6 | 37.2 | 26.7 |
