TiS3 Nanosheets

TiS3 nanosheets are different from our TiS3 crystals in that TiS3 nanosheets have been directly grown onto Ti thin foils using vapor liquid solid (VLS) growth technique. As shown in our product photos and videos, highly crystalline TiS3 nanoribbons  directly grow perpendicular to Ti foil surface in high densities. The product offer unique advantages over TiS3 as summarized below;

Advantages of TiS3 nanoribbons over TiS3 crystals

• Similar to TiS3, Ti/TiS3 nanosheets stacks can be mechanically exfoliated onto variety substrates
• VLS grown TiS3 are already really thin (~10) this mechanical exfoliation enables you to achieve monolayers much easily compared to bulk TiS3
• It is ideal for high update (battery, gas sensing / storage) applications

TiS3 is a layered material like MoS2 and other layered systems. However, the crystal displays strong crystalline anisotropy which results in direction dependent properties like thermal conductivity, electronic mobility, and excitonic binding energies. Recent studies have proposed TiS3 as high carrier mobility 2D transistors [1], new IR material [1], as well as polarized emission material [2,3]. In a typical order, a large number of layered needle like sheets are contained in a capsule sealed under Argon environment.

Crystals have been characterized by TEM, XPS, SIMS, Raman, and XRD and possess perfect 1:3 stoichiometry and defect density less than 1 defects / 10,000 unit cells.
