Gap distribution of the tunneling spectra in Bi2Sr2CaCu2Ox and some other superconductors
نویسنده
چکیده
We discuss the conductance data of superconducting single crystal Bi2Sr2CaCu2Ox obtained with a scanning tunneling microscope in the vacuum tunneling mode. For this purpose, we introduce and apply a method involving filtering techniques to study the structure of the order parameter. We find that the order parameter distribution has a rich structure spread on a large energy scale in addition to a strong peak around 30 meV.

Collective modes and quasiparticle interference on the local density of states of cuprate superconductors
The energy, momentum, and temperature dependence of the quasiparticle local density of states ~LDOS! of a two-dimensional dx22y2-wave superconductor with random disorder is investigated using the first-order T-matrix approximation. The results suggest that collective modes such as spin-charge-density waves are relevant low-energy excitations of the cuprates that contribute to the observed LDOS ...

It is a common knowledge that the formation of electron pairs is a necessary ingredient of any theoretical work describing superconductivity. Thus, finding the mechanism of the formation of the electron pairs is of utmost importance. There are some experiments on high transition temperature superconductors which support the electron-phonon (e-ph) interactions as the pairing mechanism (ARPES),...

We have investigated the electronic, magnetic, and optical properties of two Fe-based superconductors and related parent compounds via three powerful techniques: scanning tunneling microscopy/spectroscopy (STM/S), high-temperature vibrating sample magnetometry, and optical transmission spectroscopy (OTS). Below the superconducting transition temperature Tc ∼ 48 K, the STM/S of polycrystalline N...
متن کاملAndreev and single-particle tunneling spectra of underdoped cuprate superconductors.
We study tunneling spectroscopy between a normal metal and an underdoped cuprate superconductor modeled by a phenomenological theory in which the pseudogap is a precursor to the undoped Mott insulator. In the low barrier tunneling limit, the spectra are enhanced by Andreev reflection only within a voltage region of the small superconducting energy gap. In the high barrier tunneling limit, the s...

In this article a brief review of the literature on the subject is cited. The method of analysis by a finite element program is discussed in which the effect of different influential parameters are examined. The results of these computations are then compared to the corresponding empirical data and two other existing formulae for two dimensional cases. The comparisons show quite reliable and ac...
