# Pressure-induced Superconductivity in Tin Sulfide

## TL;DR

This study demonstrates that applying high pressure to tin sulfide induces an insulator-to-metal transition and superconductivity at low temperatures, confirmed through experimental synthesis and characterization.

## Contribution

First experimental observation of pressure-induced superconductivity in tin sulfide, validating theoretical predictions with detailed high-pressure transport measurements.

## Key findings

- Insulator to metal transition at 12.5 GPa
- Superconductivity observed at 47.8 GPa and 5.8 K
- Successful synthesis and characterization of SnS crystals

## Abstract

Tin sulfide (SnS) was successfully synthesized in single crystals by a melt and slow-cooling method. The obtained sample was characterized by an X-ray diffraction, an energy dispersive spectrometry, and an X-ray photoelectron spectroscopy. Electrical transport properties in SnS were investigated under high pressure using a diamond anvil cell with boron-doped metallic diamond electrodes and undoped diamond insulating layer. We successfully observed an insulator to metal transition from 12.5 GPa and pressure-induced superconductivity at 5.8 K under 47.8 GPa as predicted by a theoretical calculation.
