Abstract
Section titled āAbstractāHigh quality self-standing porous diamond film was prepared by template-free hot-filament chemical vapor deposition (HFCVD) with polyvinylpyrrolidone (PVP) as auxiliary material. The micrometer sized diamond particles were used as seed layer. And it also acted as the nucleation sites for the diamond growth. The carbon source inside the film was partially supplied by the carbonized PVP. This method breaks the bottleneck of chemical vapor infiltration, and achieves the growth of new diamond layer inside the film. Due to the high concentration of atom hydrogen, the prepared diamond porous film only contains little graphite phase. This porous diamond film can be used in many fields, such as heat sinking devices, electronic devices, and so on.
