Raman spectra of ion beam sputtered amorphous carbon thin films deposited from camphoric carbon

Oxygen permeation properties and the stability of La0.6Sr0.4Fe0.8Co0.2O3 studied by Raman spectroscopy

“…3. In the Raman spectrum, the broad peak relates to the D-line of graphite [15]. But the dark area disappeared in a few hours.…”

Catalytic methane decomposition on nickel-based model anodes of SOFCs fabricated on various oxide ion conductors

“…3, two peaks were acquired. The peaks appeared at 1580 cm − 1 and at 1355 cm − 1 is identified as graphite and disordered carbon, respectively [13,14]. For the Ni films on LSGM, ScSZ, and YSZ, the shape and the intensity of the peak at 1355 cm − 1 was similar but the intensity of the peak at 1580 cm − 1 for LSGM was lower than those for ScSZ and YSZ.…”

The a-C:H/p-Si solar cell deposited by pulsed laser deposition

“…The D-band position shifts from 1263 to 1394 cm À1 , and the G-band position shifts from 1500 to 1570 cm À1 . Some researchers reported that the upshift of D-band position is related to the decrease of bond-angle disorder [11]. According to Ferrari's theory, the upshift of G-band position is due to the evolution of the carbon film from a-C to tetrahedral amorphous carbon (ta-C), due to the change of sp 2 configuration from rings to olefinic groups [12].…”
