Waveform-sequencing for scanning tunneling microscopy based pump-probe spectroscopy and pulsed-ESR [PDF]
MethodsX, 2019 We present here the straightforward implementation of pump-probe methods into existing scanning tunneling microscopy (STM) systems. Our method uses the waveform-sequencing abilities of a standard arbitrary waveform generator (AWG) and a simple mechanical

Spin-Polarized Scanning Tunneling Microscopy: Breakthroughs and Highlights
CHIMIA, 2012 The principle of scanning tunneling microscopy, an imaging method with atomic resolution capability invented by Binnig and Rohrer in 1982, can be adapted for surface magnetism studies by using magnetic probe tips.

High dynamic range scanning tunneling microscopy [PDF]
MethodsXWe 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 ...

From a wide band gap to the superconducting proximity effect: Fe on Pb(111)
New Journal of Physics, 2023 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 ...

Controlling photocurrent channels in scanning tunneling microscopy
New Journal of Physics, 2020 We investigate photocurrents driven by femtosecond laser excitation of a (sub)-nanometer tunnel junction in an ultrahigh vacuum low-temperature scanning tunneling microscope (STM). The optically driven charge transfer is revealed by tip retraction curves
