我们报告了掺硼金刚石薄膜的扫描隧道显微镜/光谱学 (STM/STS) 实验。在 (111) 取向表面上测量的隧道电导 dI/dV 谱显示出空间变化,其分布与表面形态无关。从硼掺杂相当无序条件下超导特性的角度讨论了空间变化。
We report on scanning tunneling microscopy/spectroscopy (STM/STS) experiments on boron-doped diamond films. The tunneling conductance dI/dV spectra measured on the (111)-oriented surface show spatial variations which distribute irrespective of the surface morphology. The spatial variations are discussed in terms of characteristic features of the superconductivity under the condition of the considerable disorder by the boron doping.
