Germanium(II) Sulfide Powder CAS 12025-32-0

Germanium(II) Sulfide (GeS) is a layered semiconductor material with a direct bandgap of approximately 1.6–1.7 eV, making it suitable for optoelectronic and photovoltaic applications. It has a puckered orthorhombic crystal structure, similar to black phosphorus, which gives it unique anisotropic electrical and optical properties.

GeS exhibits strong light absorption, high carrier mobility, and excellent stability, making it a promising material for use in photodetectors, transistors, solar cells, and energy storage devices. Its two-dimensional nature also makes it a potential candidate for flexible and next-generation nanoelectronics.
