Scanning tunnelling microscopy and break-junction experiments realize metallic and
molecular nanocontacts that act as ideal one-dimensional channels between macroscopic …

A promising probe to unmask particle dark matter is to observe its effect on neutron stars, the
prospects of which depend critically on whether captured dark matter thermalizes in a timely …

Key spin transport phenomena, including magnetoresistance and spin transfer torque,
cannot be activated without spin-polarized currents, in which one electron spin is dominant …

We report measurements of the shot noise on single-molecule Au–1, 4-benzenedithiol–Au
junctions, fabricated with the mechanically controllable break junction (MCBJ) technique at …

Single atoms on Au (111) surfaces have been contacted with the Au tip of a low temperature
scanning tunneling microscope. The shot noise of the current through these contacts has …

Biased metal–molecule–metal junctions emit light through electroluminescence, a
phenomenon at the intersection of molecular electronics and nanoplasmonics. This can …

Generating highly spin-polarized currents at the nanoscale is essential for spin current
manipulations and spintronic applications. We find indications for up to 100% spin-polarized …

The development of atomic-scale structures revealing novel transport phenomena is a major
goal of nanotechnology. Examples include chains of atoms that form while stretching a …

The current I through nickelocene molecules and its noise are measured with a low-
temperature scanning tunneling microscope on a Cu (100) substrate. Density functional …

Quantum fluctuations are imprinted with valuable information about transport processes.
Experimental access to this information is possible, but challenging. We introduce the …
