Interface high-temperature superconductivity
Cuprate high-temperature superconductors consist of two quasi-two-dimensional (2D) substructures: CuO2 superconducting layers and charge reservoir layers. The superconductivity is realized by charge transfer from the charge reservoir layers into the superconducting layers without chemical dopants and defects being introduced into the latter, similar to modulationdoping in the semiconductor supe...
متن کاملHigh-temperature interface superconductivity between metallic and insulating cuprates
High-temperature superconductivity confined to nanometer-size interfaces has been a long standing goal because of potential applications 1,2 and the opportunity to study quantum phenomena in reduced dimensions 3,4. However, this is a challenging target: in conventional metals the high electron density restricts interface effects such as carrier depletion/accumulation to a region much narrower t...
متن کاملInsights from the study of high-temperature interface superconductivity.
A brief overview is given of the studies of high-temperature interface superconductivity based on atomic-layer-by-layer molecular beam epitaxy (ALL-MBE). A number of difficult materials science and physics questions have been tackled, frequently at the expense of some technical tour de force, and sometimes even by introducing new techniques. ALL-MBE is especially suitable to address questions r...
متن کاملHigh-Temperature Superconductivity
The widely held notion that high-temperature superconductivity originates in the cuprate-planes is proven to be faulty. In the cuprates such as YBa2Cu3O7, we argue that the superconductivity resides in the BaO layers. This superconductivity is s-wave, not d-wave, in the bulk. The trio of ruthenate compounds, doped Sr2YRuO6, GdSr2Cu2RuO8, and Gd2−zCezSr2Cu2RuO10 all superconduct in their SrO lay...
متن کاملHigh-temperature Anyon Superconductivity
The screening of an applied magnetic field in a charged anyon fluid at finite density (μ 6= 0) and temperature (T 6= 0) is investigated. For densities typical of high-temperature superconducting materials we find that the anyon fluid exhibits a superconducting behavior at any temperature. The total Meissner screening is characterized by two penetration lengths corresponding to two short-range e...
