Issue Date: | 2018 | Publisher: | MDPI | Source: | NANOMATERIALS, 8(9) (Art N° 653) | Abstract: | Low temperature (350 degrees C) grown conductive nanocrystalline diamond (NCD) films were realized by lithium diffusion from Cr-coated lithium niobate substrates (Cr /LNO). The NCD/Cr/LNO films showed a low resistivity of 0.01 Omega.cm and excellent field electron emission characteristics, viz. a low turn-on field of 2.3 V/mu m, a high-current density of 11.0 mA/cm(2) (at 4.9 V/m), a large field enhancement factor of 1670, and a life-time stability of 445 min (at 3.0 mA/cm(2)). The low temperature deposition process combined with the excellent electrical characteristics offers a new prospective for applications based on temperature sensitive materials. | Notes: | [Sankaran, Kamatchi Jothiramalingam; Pobedinskas, Paulius; Van Bael, Marlies K.; Haenen, Ken] Hasselt Univ, Inst Mat Res IMO, B-3590 Diepenbeek, Belgium.
