Environmentally stable, perfect, World record size single crystal SnTe₂ (Tin diselenide) crystals are developed at our facilities using state-of-art techniques. All the crystals are ready to exfoliate as shown in the images. Crystals are larger than 1cm in size giving you plenty of material to work with. In the bulk form SnTe₂2 is ~0.6-0.7 eV band gap semiconductor. Displays remarkable and unusual optical, mechanical, and electrical properties that are waiting to the published in the literature. Yet, monolayer SnTe₂ remains unknown by the scientific community and waiting to be discovered. Each crystal comes with full characterization.
