ABSTRACTSilicon carbide films are grown epitaxially on crystalline silicon substrates heated above 1000 °C, by laser ablation of pure carbon targets to thicknesses between 300 and 400 nm. These films grow on top of the silicon substrate from the carbon in the ablation plume and from the silicon of the substrate. By using a method of alternate ablation of a pure carbon and a pure silicon target, similar epitaxial films can be grown to thicknesses in excess of 1 μm with part of the silicon being supplied by the ablation plume of the silicon target.

Laser Ablation Technique

Zinc oxide (ZnO) has attractive photocatalytic properties. However, the high recombination rate of the photo-excited charge carriers on this material often restricts application. Here, we report that hybridization of one dimensional (1D) carbon nanotubes (CNT) on two dimensional (2D) porous ZnO nanosheets (NS) can be a promising strategy to overcome some of the challenges of ZnO. Specifically, a pulsed laser ablation technique was utilized to hybridize 1D CNT with 2D porous ZnO NS in environmentally friendly as well as super-economic (short time, less than 10 min) conditions. The synthesized ZnO NS-CNT hybrids show a significantly enhanced photocatalytic activity for water splitting relative to their counterpart ZnO NS.
