Abstract

We found that there is an optimum carrier density of InN for the occurrence of superconductivity. When the carrier density is within the range of 1 × 10 19cm -3 to 7×10 20cm -3, InN shows anisotropic superconductivity. The maximum transition temperature is 2.8 K and the maximum upper and lower critical fields are 2.1 T and 0.9 T, respectively. The involvement of a tetragonal In phase decreases the electron mobility and reduces the transition temperature, and moreover too much involvement destructs the superconductivity of InN.
