Our single crystal SnS (Tin sulfide) crystals come with guaranteed optical, electronic, and structural anisotropy. They are developed at our facilities using state-of-art flux zone techniques. hey are developed at our facilities using state-of-art flux zone techniques. Each growth takes close to three months to provide you perfected crystals that does not contain any transport agent (halide) impurities. In contrast to commonly used chemical vapor transport (CVT) technique, flux grown crystals are well known for their structural perfection and electronic/optical performance. Each crystal is highly crystalline, oriented in 0001 direction, and easy to exfoliate. Our R&D staff takes characterization data set in each sample piece to ensure structural, optical, and electronic consistency. 

Bridgman vs Flux zone: While both growth techniques produce superior quality materials, we recommend Bridgman grown materials as they exhibit higher electronic mobility, larger single-crystal domain size,  and lower defect concentrations. Bridgman grown samples measure 8-10mm in size. In contrast flux zone grown samples are larger in size >1 cm much higher quality compared to chemical vapor transport (commonly used method by our vendors) but exhibit higher defect concentrations (~1E10-1E11 cm-2) compared to Bridgman grown samples. Chemical vapor transport grown samples are strongly discouraged as they contain substantial amount of halide and point defects, as well as unwanted amorphous minority phases.
