InN外延层的非本征超导性：氧化铟的作用
Non-intrinsic superconductivity in InN epilayers: role of Indium Oxide
摘要：
近年来，有报道称InN半导体层中存在反常的电阻率和超导性。通过仔细的相关性的电阻率和磁化率的温度依赖性与高分辨率的X射线衍射测量的结构信息，我们表明，超导性是不是固有的InN和被认为只有在样品中，显示微量的氧杂质。因此，我们认为InN本质上不是超导半导体。
英文摘要：
In recent years there have been reports of anomalous electrical resistivity and the presence of superconductivity in semiconducting InN layers. By a careful correlation of the temperature dependence of resistivity and magnetic susceptibility with structural information from highresolution x-ray diffraction measurements we show that superconductivity is not intrinsic to InN and is seen only in samples that show traces of oxygen impurity. We hence believe that InN is not intrinsically a superconducting semiconductor.
