(a) TEM image of h-BN membrane (light gray area) on Si3N4 substrate (dark gray). The red arrow indicates an 8 nm nanopore. (b) EELS taken in regions of h-BN membrane (position indicated by blue circle in (a)) and Si3N4 substrate (red circle). (c) High resolution TEM image of a 10 nm h-BN nanopore. (d) Raman spectrum of h-BN layer transferred onto a Si substrate.
