TL;DR: In this article, a large area pulsed laser deposition growth technique was used to obtain a device-scale dielectric constant of 5.9 ± 0.65 at 1 kHz, breakdown voltage of 9.8 ± 1.0 MV cm−1, and bandgap of 4.5 eV for various thicknesses of the ultrathin amorphous boron nitride material.

TL;DR: These findings indicate that adding colloidal silica to higher breakdown strength amorphous polymers causes a reduction in dielectric strength as compared to the neat polymer, and that at these loadings failure becomes independent of polymer matrix and is dominated by silica.
