Conductance of a STM contact on the surface of a thin film

Khotkevych, N.V.; Kolesnichenko, Yu.A.; van Ruitenbeek, J.M. (Физика низких температур, 2012)

The conductance of a contact, having a radius smaller than the Fermi wave length, on the surface of a thin metal film is investigated theoretically. It is shown that quantization of the electron energy spectrum in the ...
Conductance of a tunnel point contact of noble metals in the presence of a single defect

Avotina, Ye.S.; Kolesnichenko, Yu.A.; Roobol, S.B.; van Ruitenbeek, J.M. (Физика низких температур, 2008)

In paper (Avotina et.al., Phys. Rev. B74, 085411 (2006)) the effect of Fermi surface anisotropy to the conductance of a tunnel point contact, in the vicinity of which a single point-like defect is situated, has ...
Electron tunneling into surface states through an inhomogeneous barrier: asymptotically exact solution of the problem and STM theory

Khotkevych, N.V.; Kolesnichenko, Yu.A.; van Ruitenbeek, J.M. (Физика низких температур, 2013)

We have found an asymptotically exact solution of the Schrödinger equation for electrons tunneling into surface states through an inhomogeneous barrier of large amplitude. Assuming an elliptic dispersion law for the charge ...
Influence of a single defect on the conductance of a tunnel point contact between a normal metal and a superconductor

Avotina, Ye.S.; Kolesnichenko, Yu.A.; van Ruitenbeek, J.M. (Физика низких температур, 2008)

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 scattering of quasi-particles by point-like ...
Inhomogeneous broadening of the conductance histograms for molecular junctions

Bopp, J.M.; Tewari, S.; Sabater, C.; van Ruitenbeek, J.M. (Физика низких температур, 2017)

We demonstrate that the notched-wire mechanically controllable break junction technique can be exploited for the study of single molecule junctions. We have developed a protocol for deposition of thiol-coupled molecules ...
New directions in point-contact spectroscopy based on scanning tunneling microscopy techniques (Review Article)

Tartaglini, E.; Verhagen, T.G.A.; Galli, F.; Trouwborst, M.L.; Müller, R.; Shiota, T.; Aarts, J.; van Ruitenbeek, J.M. (Физика низких температур, 2013)

Igor Yanson showed 38 years ago for the first time a point-contact measurement where he probed the energy resolved spectroscopy of the electronic scattering inside the metal. Since this first measurement, the pointconta ...
Point-contact-spectroscopy investigation of the Kondo size effect in CuCr and AuFe alloys

Fisun, V.V.; Yanson, I.K.; Mydosh, J.A.; van Ruitenbeek, J.M. (Физика низких температур, 2000)

Size effects in Kondo scattering are studied on CuCr and AuFe alloys (TK=2 K and 0.2 K, respectively) by applying point-contact spectroscopy in break-junction type contacts. It is shown that as the contact diameter is ...
Quantum interference effects in a system of two tunnel point-contacts in the presence of single scatterer: simulation of a double-tip STM experiment

Khotkevych, N.V.; Kolesnichenko, Yu.A.; van Ruitenbeek, J.M. (Физика низких температур, 2011)

The conductance of systems containing two tunnel point-contacts and a single subsurface scatterer is investigated theoretically. The problem is solved in the approximation of s-wave scattering giving analytical expressions ...
Size-effect of Kondo scattering in point contacts (revisited)

Yanson, I.K.; Fisun, V.V.; Bobrov, N.L.; Mydosh, J.A.; van Ruitenbeek, J.M. (Физика низких температур, 1998)

The size-effect of Kondo-scattering in nanometer-sized metallic point contacts is measured with the simplified, mechanically-controlled break-junction technique for CuMn alloy of different Mn concentrations: 0.017; 0.035; ...
Theory of oscillations in the STM conductance resulting from subsurface defects (Review Article)

Avotina, Ye.S.; Kolesnichenko, Yu.A.; van Ruitenbeek, J.M. (Физика низких температур, 2010)

In this review we present recent theoretical results concerning investigations of single subsurface defects by means of a scanning tunneling microscope (STM). These investigations are based on the effect of quantum ...
Микроконтактные исследования размерного эффекта Кондо в магнитном поле на сплавах CuMn, CuCr и AuFe

Фисун, В.В.; Янсон, И.К.; van Ruitenbeek, J.M.; Mydosh, J.A. (Физика низких температур, 2002)

Исследовано расщепление в магнитном поле кондо-пика на зависимости дифференциального сопротивления от напряжения на микроконтактах различного диаметра из сплавов CuMn, CuCr и AuFe. Получены эмпирические формулы, позволяющие ...
