Dly it requires additional conducive to theto a band gap of 0.70 eV. The added absorption edge and the relatively smaller band gap (0.70 eV) in the film could indicate some undetected impurities. CYM51010 Neuronal Signaling comparable outcomes analysis. have already been reported by Srivastava et al. [28], and there are actually even two or a lot more tiny band gaps in other reports [29,30]. Even so, we did not observe impurity in XRD and Raman. Table two. Atomic percentage of iron pyrite film. Consequently, the smaller sized band gap may be related towards the sulfur vacancies inside the film that had been Nanomaterials 2021, 11, x FOR PEER Evaluation 8 of 12 detected similar to the guess of de las Heras, Fe et al.

The precursor film is just not extremely continuous, with traits The surface morphologies of your precursor film and morphology are shown in of two different phases. Immediately after sulfurization, the surfaceiron pyrite film of the film alterations Figure 9a,b, respectively. The precursor film will not be really continuous, with characteristics obviously, and the film becomes even and continuous. The cross section in the film is of two various phases. Immediately after sulfurization, the surface morphology from the film adjustments shown in Figure 9c. The iron pyrite film is flat and dense.
