Report

Anomalous density of states in a metallic film in proximity with a superconductor

Autor: Gupta, A. K., Cretinon, L., Moussy, N., Pannetier, B., Courtois, H.

Publikováno v: Phys. Rev. B 69, 104514 (2004)

We investigated the local electronic density of states in superconductor-normal metal (Nb-Au) bilayers using a very low temperature (60 mK) STM. High resolution tunneling spectra measured on the normal metal (Au) surface show a clear proximity effect

Report

Local spectroscopy of a proximity superconductor at very low temperature

Autor: Moussy, N., Courtois, H., Pannetier, B.

Publikováno v: Europhys. Lett. 55, 861 (2001)

We performed the local spectroscopy of a Normal-metal--Superconductor (N-S) junction with the help of a very low temperature (60 mK) Scanning Tunneling Microscope (STM). The spatial dependence of the local density of states was probed locally in the

Report

A very low temperature STM for the local spectroscopy of mesoscopic structures

Autor: Moussy, N., Courtois, H., Pannetier, B.

Publikováno v: Rev. Sci. Instrum. 72, 128 (2001)

We present the design and operation of a very-low temperature Scanning Tunneling Microscope (STM) working at $60 mK$ in a dilution refrigerator. The STM features both atomic resolution and micron-sized scanning range at low temperature. This work is
