WebMay 27, 2024 · Hexagonal boron nitride (hBN), a graphite−like layered compound, has gained a significant amount of attention due to its unique properties such as electrical insulation with a wide band gap of ~5.9 eV, high thermal conductivity, inherent flexibility, and high temperature stability [1,2,3].The hBN film has been widely employed in deep … WebChemical vapor deposition (CVD) oxide is a linear growth process where a precursor gas deposits a thin film onto a wafer in a reactor. The growth process is low temperature and has a much higher growth rate when compared to thermal oxide. It also produces much thinner silicon dioxide layers because the film is deposted, rather than grown.
