And as a bonus, the cubic boronnitride was stable at high temperatures as well.

We use real-space nanoimaging of the polaritons in hexagonal boronnitride to demonstrate and visualize these effects.
3
Such field penetration is substantially attenuated by 2D hexagonal boronnitride, which itself has polarization in its atomic bonds.
4
However, it has been challenging to artificially develop layered materials with honeycomb atomic lattice structure composed of multicomponents such as hexagonal boronnitride.
5
Highly confined and low-loss hyperbolic phonon polaritons in hexagonal boronnitride possess properties analogous to surface plasmon polaritons, but with enhanced confinement and lower loss.
6
Here we describe crosslinked polymer nanocomposites that contain boronnitride nanosheets, the dielectric properties of which are stable over a broad temperature and frequency range.
7
Grain boundaries are observed and characterized in chemical vapor deposition-grown sheets of hexagonal boronnitride (h-BN) via ultra-high-resolution transmission electron microscopy at elevated temperature.
