Stoichiometric controlling of boroncarbonitride thin films with using BN-C dual-targets

Abstract

High carbon-rich boroncarbonitride thin films have been grown by pulsed laser deposition (PLD) technique with using BN-C dual-targets. Fourier-transform infrared (FTIR) spectroscopy results presented B-N, B-C and C-N bonds, indicating the as-deposited thin films were new ternary compounds. B-N, B-C and C-N bonding structures were also detected by X-ray photoelectron spectroscopy (XPS), and carbon content fell into a large range of 45.8 to 85.9%. The films exhibited good thermalstability in vacuum, whereas were oxidized at 600 oC in air.

Self-Ordered Orientation of Crystalline Hexagonal Boron Nitride Nanodomains Embedded in Boron Carbonitride Films for Band Gap Engineering

“…Compared to the oriented BCN film without N 2 , the intensities of the B1s and N1s core level spectra significantly increased, while the C1s decreased. As a result of the addition of nitrogen, the B-B bonds and B-O bonds disappear, and the B-N (N-B) bonds increase, which might be induced by the N atoms preferentially binding to the B atoms to form BN [29,67,68]. As a result, the thickness of the outermost amorphous layer is reduced after the addition of nitrogen.…”

Erbium energy bridging upconversion mechanism studies on BAKL:Er3+/Yb3+ glass-ceramics and simultaneous enhancement of color purity of the green luminescence

“…Similar types of vibrational modes were observed within 1200-1750 cm −1 . 27,30 This band was present due to the diborate linkage (B-O-B) in the borate glassy network. In this linkage, both boron atoms are tetrahedrally coordinated with triborate super structural units.…”

Recent advances in ternary two-dimensional materials: synthesis, properties and applications

“…37 In another work, Zhang et al fabricated BCN films with large carbon stoichiometric range using PLD with BN-N sources. 95 Huang et al developed a facile carbon-doping pyrolysis synthesis method to produce BCN nanosheets. In brief, the mixture containing glucose, boron oxide and urea was put into a tube furnace in an ammonia atmosphere for 5 h at 1250 ºC.…”
