Period-dependent suppression of Fourier peaks for topography images: Analysis of periodicity of triple-step arrays on vicinal Si(h h m) surfaces
A. Yu. Aladyshkin, A. N. Chaika, V. N. Semenov +3
Reliable determination of the periodicity of multiatomic steps on high-Miller-index vicinal surfaces is often complicated by (i) the presence of relatively narrow terraces tilted a…
Atomically precise triple-step staircase on a vicinal silicon surface: Is it Si(5 5 7), Si(7 7 10) or Si(8 8 11)?
A. N. Chaika, A. Yu. Aladyshkin, V. N. Semenov +3
Scanning tunneling microscopy studies of periodic arrays of triple steps fabricated on single-crystalline Si(5 5 7) wafers demonstrate several possible atomic structures of consecu…
Effective removal of global tilt from topography images of vicinal surfaces with narrow terraces
A. Yu. Aladyshkin, A. N. Chaika, V. N. Semenov +2
The main feature of vicinal surfaces of crystals characterized by the Miller indices (hhm) is rather small width (less than 10 nm) and substantially large length (more than 200 nm)…
Visualization of Atomic Structures on Faceted and Nonflat Surfaces by the Difference-of-Gaussians Approach
A. Yu. Aladyshkin, A. N. Chaika, V. N. Semenov +3
Detailed analysis of scanning probe microscopy (SPM) data acquired for faceted and non-flat surfaces is usually complicated due to the presence of a large number of surface areas t…
Observation of hidden parts of dislocation loops in thin Pb films by means of scanning tunneling spectroscopy
A. Yu. Aladyshkin, A. S. Aladyshkina, S. I. Bozhko
Local electronic properties of quasi-two-dimensional Pb(111) islands with screw dislocations of different types on their surfaces were experimentally studied by means of low-temper…
Step bunching with both directions of the current: Vicinal W(110) surfaces versus atomistic scale model
Olzat Toktarbaiuly, Victor Usov, Cormac Ó Coileáin +14
We report for the first time the observation of bunching of monoatomic steps on vicinal W(110) surfaces induced by step up or step down currents across the steps. Measurements reve…
Double Fe-impurity charge state in the topological insulator BiSe
V. S. Stolyarov, S. V. Remizov, D. S. Shapiro +10
The influence of individual impurities of Fe on the electronic properties of topological insulator BiSe is studied by Scanning Tunneling Microscopy. The microscope tip is u…
Fabrication of sharp atomic force microscope probes using in-situ local electric field induced deposition under ambient conditions
Alexei Temiryazev, Sergey I. Bozhko, A. Edward Robinson +1
We demonstrate a simple method to significantly improve the sharpness of standard silicon probes for an atomic force microscope, or to repair a damaged probe. The method is based o…
Surface states in a 3D topological insulator: The role of hexagonal warping and curvature
E. V. Repin, V. S. Stolyarov, T. Cren +5
We explore a combined effect of hexagonal warping and of finite effective mass on both the tunneling density of electronic states (TDOS) and structure of Landau levels (LLs) of 3D…
Remarkable effects of disorder on superconductivity of single atomic layers of lead on silicon
C. Brun, T. Cren, V. Cherkez +8
In bulk materials superconductivity is remarkably robust with respect to non-magnetic disorder. In the two-dimensional limit however, the quantum condensate suffers from the effect…
