简单介绍


ossila二硫化锗粉体  的详细介绍

Nanoflakes of 2D GeS2 with a thickness of 4.2 nm achieved via mechanical exfoliation is expected to show strong in-plane anisotropy in electrical, optical, and mechanical properties and has been used as polarization-sensitive photo-detectors in the short wave region.

We supply low price germanium disulfide in several different forms for a range of applications.

Germanium disulfide powder

Germanium Disulfide Powder

Can be used for preparation of germanium disulfide nanoplates and ultrathin films

Sold by weight

≥99.995% purity

Germanium disulfide crystal

Germanium Disulfide by Size

Can be used to produce single or few-layer germanium disulfide sheets via mechanical or liquid exfoliation

Small (≥10 mm2) or medium (≥25 mm2) crystals available*

≥99.999% purity

*Typical representative size, areas/dimensions may vary

Bulk single germanium disulfide crystal is most commonly used as sources from which single or few-layer sheets can be obtained via either mechanical or liquid exfoliation.

Germanium disulfide powder can also be used to prepare GeS2 nanosheets and nanoparticles by liquid-exfoliation (normally assisted by sonication).
