Description

Description Hexagonal boron nitride is a semiconductor with a direct band gap of about 5.9 eV. These layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers, up to monolayers of h-BN.

Features And Benefits

Features And Benefits Our h-BN crystals have typical lateral dimensions of about 0.1 cm and are transparent. Single crystal h-BN is an excellent insulator with very large breakdown voltage (>0.4 V/nm). Large-area-sized h-BN single crystals can be exfoliated onto substrates. For crystals with thicknesses of tens of nanometers thick, the size ranges up to ~100 μm.

Application

Application h-BN has been widely used as an insulator for the production of ultra-high mobility 2D heterostructures composed of various types of 2D semiconductors.
