Quantum dot scanning tunneling microscopy for Majorana bound states in continuum
Frontiers in Physics, 2022 We propose a device composed of a quantum dot (QD) connected to a normal metal lead to detect Majorana bound states (MBSs), which are formed at the ends of a topological superconductor nanowire (TSNW) and coupled to the lead with spin-dependent ...

Sub-monolayer film growth of a volatile lanthanide complex on metallic surfaces
Beilstein Journal of Nanotechnology, 2015 We deposited a volatile lanthanide complex, tris(2,2,6,6-tetramethyl-3,5-heptanedionato)terbium(III), onto metal surfaces of Cu(111), Ag(111) and Au(111) in vacuum and observed well-ordered sub-monolayer films with low temperature (5 K) scanning ...

Combined I(V) and dI(V)/dz scanning tunneling spectroscopy
AIP Advances, 2018 We present a method to simultaneously record I(V) and dI(V)dz spectra in a scanning tunneling microscopy measurement, where I, V and z refer to the tunnel current, sample bias and tip-substrate separation, respectively.

Introduction to Scanning Tunneling Microscopy [PDF]
, 1993 AbstractThe scanning tunneling microscope (STM) and the atomic force microscope (AFM), both capable of visualizing and manipulating individual atoms, are the cornerstones of nanoscience and nanotechnology today. The inventors of STM, Gerd Binnig and Heinrich Rohrer, were awarded with the Nobel Prize of physics in 1986.

High dynamic range scanning tunneling microscopy
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 ...
