Research Abstract |
This study has been carried out in order to develop the technique that grows the standalone high-quality hexagonal BN (h-BN) crystals by selective growth. The h-BN films were grown on c-plane sapphire substrates by chemical vapor deposition. It has been found that the structural and luminescent properties are strongly correlated with each other. The low pressure growth successfully yielded the thick films with a unique in-plane orientation for the first time. The lateral growth was also enhanced under the reduced pressure. The re-growth at high temperatures on the separated films was also proven to be a promising technique to yield the large-area crystals with higher structural properties.
