2019年9月20日 · Surface chemical states of the SnSSe/rGO electrode was assessed by using XPS technology. As shown in Fig. 3 a, the strong C signal derived from the rGO matrix and the …

2021年9月1日 · The electronic structure and composition of the SnSSe/MGS, SnSSe/CNT, and SnSSe/CNP were characterized by XPS (Figs. 4, S6, and S7). Fig. 4 (a) shows that the main …

2022年8月5日 · Herein, 2D SnSSe (SSS) porous nanoplates (Sn: S: Se=1: 1: 0.5) with atom-level heterojunctions were obtained from optimized hydrothermal synthesis, and a novel SSS-based …

X-ray photoelectron spectroscopy (XPS) is considered to be an effective method in the determination of elemental composition. The broadband XPS spectrum of SnSSe is...

2019年4月5日 · XPS analyses confirmed the presence of Sn, S and Se elements on the surface of the film. The bandgap of the films was calculated from the optical transmittance in the …

In particular, based on a MoS2 monolayer, the authors fully replace the top-layer S with Se atoms. The authors confirm the Janus structure of MoSSe directly by scanning TEM and energy …

2023年2月14日 · In this work, we report the low-pressure PVD synthesis of high-quality 2D SnSe crystals with thinner thickness and larger lateral sizes. The as-synthesized SnSe displays high …

The X-ray photoelectron spectroscopy (XPS) is considered to be an effective method in the determination of elemental composition. The broadband XPS spectrum of SnSSe is shown in …

The occurrence of Sn-S polytypes was examined using Raman and XPS studies. Annealing causes changes in the optical properties, as observed through optical analysis, which can be …

The GaN/SnS 2 /SnSSe heterojunction showcases a staircase-like (type-II) band alignment and exceptional performance metrics: high photoresponsivity of 314.96 A W −1, specific detectivity …
