Device-Grade Hexagonal Boron Nitride (hBN) Single Crystal is an ultra-high-quality layered crystal material engineered for next-generation electronic, photonic, and quantum technologies. Produced through a proprietary atmospheric-pressure crystal growth process, these millimeter-scale single crystals exhibit exceptional structural integrity, low defect density, and outstanding dielectric and optical properties.
As one of the most important van der Waals materials, hBN serves as an ideal substrate and encapsulation layer for graphene and other two-dimensional materials. Its atomically flat surface, chemical inertness, and wide bandgap make it indispensable in the fabrication of high-performance electronic devices and advanced research platforms.
Independent studies have demonstrated that graphene devices fabricated on these crystals achieve carrier mobilities comparable to or exceeding those obtained using internationally recognized benchmark hBN materials.
