Description
We provide the world's largest size commercially available In2Se3 crystals at the highest quality In2Se3 and affordable prices. Our crystals exceed competing crystals both in size and quality.
In2Se3 crystals now available in Bridgman grown (highest quality) and chemical vapor transport (lower grade) options
Description
In2Se3 single crystals were grown using Bridgman or chemical vapor transport (CVT) techniques. These crystals are largest in the commercial market with high attention given to having best electronic and optical quality. Unlike other In2Se3, the phase of this product is controlled carefully by after meticulous synthesis refinement steps and the flakes are highly crystalline. Flakes are perfectly layered, in-plane sheets are perfectly aligned in the (002) direction as determined by XRD and 4-angle XRD (rocking curves). In the bulk, the crystals display 1.41 eV band gap and show strong Raman peaks.
