We provide the world's largest size commercially available InSe crystals at the highest quality InSe and affordable prices. Our crystals exceed competing crystals both in size and quality.

Description

Our single crystal gamma phase InSe crystals come with guaranteed optical, electronic, and structural quality. They are developed at our facilities using three different state-of-art techniques: i) Bridgman growth abd ii) chemical vapor transport (CVT) growth. The latter (CVT) produces contaminated samples around centimeters in size. Bridgman method offers superior crystallinity (recommended method). Each crystal is highly crystalline, oriented in 0001 direction, and easy to exfoliate. Our R&D staff takes characterization dataset in each sample piece to ensure structural, optical, and electronic consistency.
