Phase controllable synthesis of SnSe and SnSe2 films with tunable photoresponse properties

Atmospheric pressure chemical vapor deposition growth of vertically aligned SnS2 and SnSe2 nanosheets

“…Concerning the second contribution in Se signal, at 54.8 eV, this contribution is not fully understood in the literature. If this contribution could be attributed to SnSe phase, in agreement with, 36 one should also see a contribution in the Sn signal, at lower binding energy (shifted by ≈ −0.7 eV). The Se contribution cannot be attributed to SeO 2 , as this contribution is centered at much higher binding energy, around 59.5 eV.…”

“…35 Within this perspective, using SnSe as tin precursor, the crystallographic phase was ne controlled by tuning the control by synthesis temperature. 36 Furthermore, using diethethyl selenide with SnCl 4 as precursor for the synthesis, a vertical preferential growth of SnSe 2 was observed. 37 A different CVD strategy for the synthesis of metal dichalcogenides is direct sulfurization 27 or selenization 38 of metal lms.…”

Photosensing and Characterizing of the Pristine and In-, Sn-Doped Bi2Se3 Nanoplatelets Fabricated by Thermal V–S Process

“…Figure 4d presents XPS spectra of Sn 3d. Peaks at 485.1 and 493.7 eV are associated with the Sn 2+ 3d 5/2 and Sn 2+ 3d 3/2 orbitals, respectively, of the SnSe phase [52]. Peaks at 486.6 and 495.1 eV are associated with the Sn 4+ 3d 5/2 and Sn 4+ 3d 3/2 orbitals of the SnSe2 phase [53].…”

Charge density wave in a SnSe2 layer on and the effect of surface hydrogenation

“…42–45 For example, SnSe 2 and SnSe can be produced by micromechanical exfoliation, 46,47 a solvothermal approach, 48 and vapor deposition (VD). 49,50 SnSe 2 and SnSe can be also found together with thermal annealing and these have been observed by Raman spectroscopy. 51 In experimental and theoretical studies, junction formation with n-type SnSe 2 and p-type SnSe can be established.…”
