Fitting results of the Raman spectra for various samples
| Substrate | Peak (D) (cm−1) | Peak (G) (cm−1) | ID/IG | I2D/IG | FWHM (G) (cm−1) | FWHM (2D) (cm−1) |
|---|---|---|---|---|---|---|
| SrTiO3 | 1,372 | 1,603 | 0.8 | - | 70 | - |
| YSZ | 1,364 | 1,609 | 1.1 | - | 63 | - |
| SiO2 | 1,352 | 1,598 | 1.9 | 0.4 | 66 | 96 |
| Glass | 1,352 | 1,598 | 1.8 | 0.3 | 66 | 99 |
Mixed Gaussian and Lorentzian functions are used to fit D, G, and 2D peaks. FWHM, full width at half maximum.
