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.

Application


  • New flexible and transparent solution-based germanium-sulfide polymeric materials: This research presents the successful preparation of solution-based polymeric germanium sulfide materials, showcasing their potential applications in flexible and transparent electronics (DTB De Salvi, AE Job, SJL Ribeiro, 2015).

  • Germanium monosulfide as a natural platform for highly anisotropic THz polaritons: Introduces alpha-germanium(II) sulfide (GeS) as a promising candidate for enhancing THz nanospectroscopy, significantly impacting materials science and optoelectronic device development (T Nörenberg et al., 2022).
