How can Hbn be used in a practical application?
p towards the practical application of hBN is the on-demand, position-controlled generat on of SPEs. Several strategies have been reported to achieve the deterministic creation of hBN SPEs. However, they either rely on a substrate nanopatterning procedure that is not compatible with integrated photonic devices

What is HBN used for?
However, hBN with thicknesses greater than a monolayer is desirable for most applications, such as a gas-diffusion barrier 15, an oxidation-protecting layer 16, an encapsulation layer 17, a dielectric substrate for 2D semiconductors 10, 11, 12 and a capacitor for resistive random access memory 18.

What is a phonon in hBN?
In hBN, the TO (E 1u) phonon at 7.3 μm corresponds to in-plane atomic motion parallel to the zigzag axis (Fig. 1B, inset) where boron and nitrogen displace in opposite directions. This optical phonon is dipole active and lies in the laser-accessible mid-IR regime due to the material’s light constituent atoms.

How is HBN annealed?
The hBN was then annealed under a H 2 –Ar mixed flow (10% H 2) at 300 °C for 3 h before stacking monolayer graphene. This resulted in a cleaner hBN surface by removing small nanoparticles, probably originating from the PMMA residue (Extended Data Fig. 1).

How is HBN transferred?
First, the as-grown hBN is protected by a polymethyl methacrylate (PMMA) film and electrochemically delaminated in a 1 M NaOH solution 45. For comparison, hBN was also transferred by the chemical etching of Fe–Ni in FeCl 3 –HCl (0.2 M:2.0 M) solution. The PMMA/hBN was then transferred on a SiO 2 /Si substrate and PMMA was removed with hot acetone.
