我们报告了由掺硼超导金刚石制成的纳米结构的输运特性。从通过化学气相沉积生长的纳米晶超导硼掺杂金刚石薄膜开始，我们通过尺寸在纳米范围内的电子束光刻设备进行图案化。我们表明，即使对于如此小的设备，材料的超导特性也得到了很好的保留：对于宽度小于 100 nm 的导线，我们测量了开尔文范围内的临界温度和特斯拉范围内的临界场。
We report on the transport properties of nanostructures made from boron-doped superconducting diamond. Starting from nanocrystalline superconducting boron-doped diamond thin films, grown by chemical vapour deposition, we pattern by electron-beam lithography devices with dimensions in the nanometer range. We show that even for such small devices, the superconducting properties of the material are well preserved: for wires of width less than 100 nm, we measure critical temperatures in the kelvin range and critical fields in the tesla range.
