摘要：

Tin sulfide (SnS) single crystals were synthesized using a melt and slow-cooling method. The obtained crystals were characterized by x-ray diffraction, energy-dispersive spectrometry, and by x-ray photoelectron spectroscopy. Electrical transport properties of SnS were investigated under high pressure using a diamond anvil cell with boron-doped metallic diamond electrodes and an undoped diamond insulating layer. We successfully observed an insulator to metal transition between 8.1 and 12.5 GPa and pressure-induced superconductivity with a transition temperature (T-c) of 5.8 K under 47.8 GPa as predicted by theoretical calculations. Comparing with the pressure-induced superconductivity in related SnSe compound, a possible T-c enhancement in SnS by an increase of density of states at the Fermi level is expected.
