Abstract
Hexagonal boron nitride (hBN), also known as white graphite, is a
transparent layered crystal with a wide bandgap. Its crystal structure
resembles graphite, featuring layers composed of honeycomb lattices
held together through van der Waals forces. The layered crystal
structure of hBN facilitates exfoliation into thinner flakes and makes
it highly anisotropic in in-plane and out-of-plane directions. Unlike
graphite, hBN is both insulating and transparent, making it an ideal
material for isolating devices from the environment and acting as a
waveguide. As a result, hBN has found extensive applications in
optical devices, electronic devices, and quantum photonic devices.
This comprehensive tutorial aims to provide readers with a thorough
understanding of hBN, covering its synthesis, lattice and
spectroscopic characterization, and various applications in
optoelectronic and quantum photonic devices. This tutorial is designed
for both readers without prior experience in hBN and those with
expertise in specific fields seeking to understand its relevance and
connections to others.
