    摘要: C-axis oriented InN films with wurtzite structure were grown on sapphire (0001) substrate by MOCVD method. Superconductivity with transition onset temperature Tc,onset around 3.5 K has been characterized by magnetotransport measurements in fields up to 9 Tesla for films with carrier concentration in the range of 1×1019 cm–3 to 7×1020 cm–3. Among them, the film with a nitridation buffer layer has the highest zero-resistance temperature Tc0 of 2 K. The normal-state magnetoresistance follows Kohler's rule ΔR /R ∝ (H /R)2, indicating that there is a single species of charge carrier with single scattering time at all points on the Fermi surface. The extrapolated value of zero-temperature upper critical field Hc 2ab (0) and Hc 2c (0) is estimated to be 5900 G and 2800 G, respectively, giving rise to the anisotropy parameter about 2.1. The angular dependence of the upper critical field is in good agreement with the behavior predicted by Lawrence-Doniach model in the two-dimensional (2D) limit strongly suggesting that the InN film is a quasi-2D superconductor.
