Product Overview

Germanium Sulphide (GeS) is a layered semiconductor known for its indirect band gap near 1.6 eV. Its crystal structure consists of stacked layers held by van der Waals forces, allowing exfoliation into ultrathin 2D sheets. This unique feature places GeS among group-14 transition metal monochalcogenides with distinctive electronic and optical properties.

Stanford Optics supplies high-purity GeS crystals suited for research and development in optoelectronics and nanoelectronics.
