General description

Differential thermal analysis of germanium (II) sulfide was investigated. Melting point of GeS is 665oC. GeS nanoparticles may be prepared by gas phase laser photolysis, to be used in lithium ion batteries. GeS films may be generated by electrochemical deposition and used as an electrolyte. A study also reports the formation of GeS clusters by laser ablation.

Germanium sulfide clusters were generated by laser ablation of a solid sample. The resulting molecules were analyzed in a time-of-flight mass spectrometer. In addition to atomic germanium and diatomic sulfur, the spectra exhibited evidence for the existence of clusters containing...

A facile room-temperature electrochemical deposition process for germanium sulfide (GeS(x)) has been developed with the use of an ionic liquid as an electrolyte. The electrodeposition mechanism follows the induced codeposition of Ge and S precursors in ionic liquids generating GeS(x)...
