Raman spectrum of monoclinic semiconductor Cu2SnSe3

Cu2SnSe3 and alloyed (ZnSe)x(Cu2SnSe3)1−x nanocrystals with a metastable zincblende and wurtzite structure

“…1a shows the X-ray diffraction (XRD) patterns of as-prepared Cu 2 SnSe 3 nanocrystals with a zincblende and wurtzite structure. Note that our experimental patterns are totally different from that of bulk monoclinic Cu 2 SnSe 3 [11][12][13][14], and no peaks corresponding to monoclinic structure were observed. Therefore, we simulated XRD patterns for zincblende and wurtzite Cu 2 SnSe 3 .…”

“…One of these compounds, Cu 2 SnSe 3 which usually crystallizes in a monoclinic [11][12][13][14] or zincblende [15][16][17][18] structure has been extensively studied with a band gap of 0.96 eV [18]. However, this value of the band gap is not suitable for the photovoltaic application [19].…”

Epitaxial Cu 2 ZnSnSe 4 thin films and devices

“…This mode is commonly attributed to a monoclinic Cu 2 SnSe 3 [9]. However, all Raman peak positions have to be shifted by 3 cm −1 to higher wavenumbers in order to From the compositional point of view this result is nothing but expected.…”

“…However, one has to be careful since CTSe can exist in different modifications. A monoclinic Cu 2 SnSe 3 has been reported by Marcano et al [9]. Moreover cubic Cu 2 SnSe 4 [10], cubic Cu 2 SnSe 3 [11] and a low temperature orthorhombic modification [12] have been reported.…”

The AACVD of CFTS Family of Materials

“…19,20 Varying the Fe: Zn in CFTS and S:Se ratio in CZTS can tune both the band gap and lattice parameter. [18][19][20][21][22] Herein we report the thin films deposition of this multinary family of materials by AACVD and the investigation of different parameters affecting the phase, morphology, band gap and electrical resistance of these materials. …”
