Pressure-induced metallization and enhanced photoelectric activity in layered tin disulfide

Applied Physics Letters, Journal Year: 2024, Volume and Issue: 124(9)

Published: Feb. 26, 2024

Two-dimensional layered metal dichalcogenides have given rise to considerable interest in electronics and optoelectronics fields because of their excellent physical chemical properties promising applications. Tin disulfide (SnS2) is an important member them due its environment-friendly resource-rich characteristics. Here, a series situ electrical transport experiments photocurrent measurements under high pressure been performed investigate the opto-electrical 4H-SnS2. With increasing pressure, resistivity 4H-SnS2 decrease significantly, leading transition from semiconducting metallic state above 58.6 GPa. The increase results substantial enhancement photoelectric activity, indicating extensive potential utilizing as trigger for optoelectronic Combined with our previous x-ray diffraction optical absorption at pressure-induced structural distortion, bandgap narrowing, metallization, activity are tunable reversible, which great significance both fundamental research device design.

Water-Based Bi2S3 Nano-Inks Obtained with Surfactant-Assisted Liquid Phase Exfoliation and Their Direct Processing into Thin Films

Colloids and Interfaces, Journal Year: 2024, Volume and Issue: 8(3), P. 28 - 28

Published: April 30, 2024

Bi2S3 has gained considerable attention as a semiconductor for its versatile functional properties, finding application across various fields, and liquid phase exfoliation (LPE) serves straightforward method to produce it in nano-form. Till now, the commonly used solvent LPE been N-Methyl-2-pyrrolidone, which is expensive, toxic high boiling point. These limitations drive search more sustainable alternatives, with water being promising option. Nonetheless, surfactants are necessary due hydrophobic nature of Bi2S3, organic molecules amphoteric characteristics identified suitable surfactants. However, systematic studies on use ionic have remained scarce until now. In this work, we sodium dodecyl sulfate (SDS), dodecylbenzene sulfonate (SDBS) hexadecyl (SHS) representative species present comprehensive investigation into their effects Bi2S3. Through characterizations resulting products, find that all effectively exfoliate few-layer species. Notably, SDBS demonstrates superior stabilization 2D layers compared other surfactants, while SHS becomes most surfactant obtaining products yield. Moreover, nano-inks fabricating films using spray-coating, reaching fine tuning band gap by controlling number cycles, paving way utilization optoelectronic devices.
