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 ...

Investigation of the unusual magnetic properties of Fe and Co on MgO with high spatial, energy and temporal resolution [PDF]
, 2015 Nanometer-sized magnets are used as magnetic bits in data storage devices to hold information. As such devices are further miniaturized, the control of magnetism at the atomic scale becomes essential.

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.
