Al超导针尖的扫描隧道谱

Scanning tunneling spectroscopy with superconducting tips of Al

I. Guillamon, H. Suderow, S. Vieira, P. Rodiere

摘要:

本文报道了0.1K下用Al针尖的扫描隧道谱测量,在零场下观察到了2HNbSe_2的原子晶格和电荷密度波,在磁场下精确地分辨出了涡旋特有的电子表面性质。尖端态密度受涡旋的局部磁场的影响,为纳米尺度下的磁场提供了新的探针。

英文摘要:

We present Scanning Tunneling Spectroscopy measurements at 0.1 K using tips made of Al. At zero field, the atomic lattice and charge density wave of 2HNbSe2 are observed, and under magnetic fields the peculiar electronic surface properties of vortices are precisely resolved. The tip density of states is influenced by the local magnetic field of the vortex, providing for a new probe of the magnetic field at nanometric sizes.
