By reducing Tg, the peak at 2θ = 26.2° is appeared, which is considered to the turbostratic BN (t‐BN). The interlayers of 1.0 nm AlON are identified between BN layers and Al2O3 substrate. ChemiDay you always could choose go nuts or keep calm with us or without. The boron nitride (BN) thin films on Al 2 O 3 substrates grown by chemical vapor deposition (CVD) using alternating supply of B 2 H 6 and NH 3 are investigated. The Action of Ammonia on the Methyl Diboranes, Hydrides of Boron. Use the link below to share a full-text version of this article with your friends and colleagues. When B 2 H 6 reacts with excess of NH 3 at high temperature , boron nitride (BN) is formed and H 2 is evolved. I.
