The observation by scanning tunnelling spectroscopy of Abrikosov vortex cores in the high-temperature superconductor YBa2Cu3O7−δ (Y123) has revealed a robust pair of electron-hole symmetric states at finite subgap energy. Their interpretation rema

In this paper, we present a new numerical model, in which both the thermal and the electromagnetic aspects of the over-critical current regime of HTS materials are taken into account. The electromagnetic and thermal equations have been implemented in

Control of the density of mobile charge carriers using electric fields is widely used in a variety of metal-insulator-semiconductor structures and is the governing principle behind the operation of field-effect transistors. Ferroelectric materials po

Recently, much attention has been paid to inhomogeneity in samples of the high-temperature superconductor Bi2Sr2CaCu2O8+δ. In this work it is shown that homogeneous samples can indeed be obtained in the slightly overdoped range. However, the homogen

Using scanning tunneling spectroscopy, we investigated the temperature dependence of the quasiparticle density of states of overdoped ${\mathrm{Bi}}_{2}{\mathrm{Sr}}_{2}{\mathrm{CuO}}_{6+\ensuremath{\delta}}$ between 275 mK and 82 K. Below ${T}_{c}\p

We have studied the properties of superconducting strip lines, based on epitaxial YBCO thin films, at high current densities. Experiments performed with short constant current pulses show that a quasi spontaneous highly dissipative state (HDS) appear

We present a detailed study on the behavior of vortex cores in Bi2Sr2CaCu2O8+δ using scanning tunneling spectroscopy. The very irregular distribution and shape of the vortex cores imply a strong pinning of the vortices by defects and inhomogeneities

During past years, scanning tunneling spectroscopy (STS) investigations of high temperature superconductors have revealed unusual characteristics of the superconducting gap. We present here the temperature dependence of the tunneling conductance spec

Scanning tunneling spectroscopy allows us to study the changes in the quasiparticle local density of states due to the presence of vortex cores in Bi2Sr2CaCu2O8+δ (BSCCO). The vortex core spectra are characterized by a gap-like structure similar to

We report on the preparation and characterization of epitaxial ACuO2 (A = Sr, Ca, Ba) thin films and multilayers with the so- called infinite layer (IL) structure, by rf magnetron sputtering. Films and multilayers without Ba have a remarkable crystal
