Figure 4

(a) Normalized Raman spectra of the surface of Sb2Se3 thin films with 2[Se]/(2[Se] + 3[Sb]): 0.36, 0.48, 0.50, 0.53, and 0.54. (b) Area of Raman peaks—expressed as A(peak of interest)/A(190 cm–1) as a function of 2[Se]/(2[Se] + 3[Sb]). (c) Absolute Raman spectra of lift-off remain on the Mo substrate of Sb2Se3 samples with 2[Se]/(2[Se] + 3[Sb]): 0.50, 0.52, 0.53, and 0.54. (d) Absolute Raman spectra of the previous peeled-off Sb2Se3 films. (e) Texture coefficient (002) as a function of 2[Se]/(2[Se] + 3[Sb]).
