Electrochemical Scanning Tunneling Microscopy
The electrochemical scanning tunneling microscope was the first tool for the investigation of solid–liquid interfaces that allowed in situ real space imaging of electrode surfaces at the atomic level.

High dynamic range scanning tunneling microscopy [PDF]
We increase the dynamical range of a scanning tunneling microscope (STM) by actively subtracting dominant current-harmonics generated by nonlinearities in the current-voltage characteristics that could saturate the current preamplifier at low junction ...

Investigation of electron-induced cross-linking of self-assembled monolayers by scanning tunneling microscopy [PDF]
Ultrathin membranes with subnanometer pores enabling molecular size-selective separation were generated on surfaces via electron-induced cross-linking of self-assembled monolayers (SAMs).

Scanning tunneling microscopy [PDF]
A scanning tunneling microscope (STM) can provide atomic-resolution images of samples in ultra-high vacuum, moderate vacuum, gases including air at atmospheric pressure, and liquids including oil, water, liquid nitrogen, and even conductive solutions.

From a wide band gap to the superconducting proximity effect: Fe on Pb(111)
Epitaxially grown Fe nanostructures on Pb(111) were studied by low-temperature scanning tunneling microscopy and spectroscopy. The deposited Fe assemblies are classified into two groups according to their electronic behavior close to the Fermi energy ...

Scanning tunneling microscopy.
Abstract Scanning Tunneling Microscopy (STM) is a new method for studying surface phenomena in semiconductors and metals on an atomic scale. A metal tip is scanned over the surface at such a small distance that a tunneling current in the nanoamp range flows under application of a voltage between tip and sample. Surface areas are scanned by moving the
