Comprehensive Study

We report on a comprehensive study of the properties of quasi-freestanding monolayer and bilayer graphene produced by conversion of the (6√3×6√3)R30° reconstruction into graphene via intercalation of hydrogen. The conversion is confirmed by photoelectron spectroscopy and Raman spectroscopy. By using infrared absorption spectroscopy we show that the underlying SiC(0001) surface is terminated by hydrogen in the form of Si-H bonds. Using Hall effect measurements we have determined the carrier concentration and type as well as the mobility which lies well above 1000 cm2/Vs despite a significant amount of short range scatterers detected by Raman spectroscopy.

The Impact

This work reports a general and effective strategy of determining the intrinsic Stark tuning rate by removing the impact of the dynamical coupling of adsorbed CO on the Cu surface with surface enhanced infrared absorption spectroscopy (SEIRAS).

AbstractWe report the structure of 5,5′-bis(4-hydroxyhexylphenyl)-2,2′-bithiophene (HO6PTTP60H) powder and sublimated films studied by X-ray diffraction (XRD) and Infrared absorption spectroscopy (IRAS). From XRD, herringbone packing is observed for the HO6PTTP60H powder. Different layer spacing is found for the powder (33.1Å) and the sublimated film (26.5Å). This slight difference indicates that the HO6PTTP60H molecule is tilted in the film. IRAS results confirm the presence of the HO6PTTP6OH molecule on the surface and its good stability over a few days.

A new series of double malonates of some of the lanthanides and yttrium with sodium having the formula Na5Ln(C3H2O4)4•7•5 H2O was synthesised. The compounds were characterised using X-ray powder diffractometry and infrared absorption spectroscopy.
