Crystalline Hexagonal Boron Nitride with 98% Nitrogen-15 Isotope Enrichment

Crystalline Hexagonal Boron Nitride with 98% Nitrogen-15 Isotope Enrichment

Abstract

While hexagonal boron nitride (hBN) fine powders and fine grain solids have been commercial products for over six decades, recently, there has been a heightened interest in crystalline hBN for special high-tech applications in quantum temperature, pressure, and magnetic sensing.In a significant breakthrough, researchers at Kansas State University have developed crystalline hexagonal boron nitride highly enriched (>98%) with the nitrogen-15 isotope (hB15N). In contrast, commercial hBN contains only 0.4% nitrogen-15 isotope. K-State’s isotope enriched crystalline hB15N has a higher thermal conductivity and lower nuclear spin density than hBN with the natural distribution of isotopes.

The synthesis of 15N enriched hBN in any form, including powders, is very rare. The process developed by K-State researchers produces high quality, large area crystalline hB15N that can enable better and new types of hBN-based electronic, optoelectronic, nanophotonic, and quantum devices.

Benefit

Improved Quantum Sensors – Since it is a two-dimensional material, hB15N offers substantially better sensitivity and spatial resolution than three-dimensional quantum diamonds for micro nuclear magnetic resonance (NMR).Improved Biological Applications – With its lower nuclear spin density, hB15N, offer improved performance for detecting paramagnetic spins – unpaired electrons. This makes it better for biological applications such as detecting trace concentrations of ions in solutions, monitoring free radical generation in cells, and measuring iron load in ferritin proteins.

Semiconductor & Supercomputing applications – With controlled isotope concentrations, hBN has an enhanced thermal conductivity, makes it highly efficient at dissipating heat. Incorporated into printed circuit broads, this will significantly improve computing speed and efficiency.
