Theory of oscillations in the STM conductance resulting from subsurface defects (Review Article)
Ye. S. Avotina, Yu. A. Kolesnichenko, J. M. van Ruitenbeek
In this review we present recent theoretical results concerning investigations of single subsurface defects by means of a scanning tunneling microscope (STM). These investigations…
Influence of a single defect on the conductance of a tunnel point contact between a normal metal and a superconductor
Ye. S. Avotina, Yu. A. Kolesnichenko, J. M. van Ruitenbeek
We have investigated theoretically the conductance of a Normal-Superconductor point-contact in the tunnel limit and analyzed the quantum interference effects originating from the s…
The signature of subsurface Kondo impurities in the local tunnel current
Ye. S. Avotina, Yu. A. Kolesnichenko, J. M. van Ruitenbeek
The conductance of a tunnel point-contact in an STM-like geometry having a single defect placed below the surface is investigated theoretically. The effect of multiple electron sca…
Conductance of a tunnel point-contact of noble metals in the presence of a single defect
Ye. S. Avotina, Yu. A. Kolesnichenko, S. B. Roobol +1
In paper [1] (Avotina et al. Phys. Rev. B,74, 085411 (2006)) the effect of Fermi surface anisotropy to the conductance of a tunnel point contact, in the vicinity of which a single…
Signature of Fermi surface anisotropy in point contact conductance in the presence of defects
Ye. S. Avotina, Yu. A. Kolesnichenko, A. F. Otte +1
In a previous paper (Avotina et al.,Phys. Rev. B Vol.71, 115430 (2005)) we have shown that in principle it is possible to image the defect positions below a metal surface by means…
Method to determine defect positions below a metal surface by STM
Ye. S. Avotina, Yu. A. Kolesnichenko, A. N. Omelyanchouk +2
The oscillatory voltage dependence of the conductance of a quantum point contact in the presence of a single point-like defect has been analyzed theoretically. Such signals are det…
