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 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 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 کاملDynamical screening at the metal–semiconductor interface and excitonic superconductivity
We examine the possibility of excitonic superconductivity at a metal–semiconductor interface. An ab initio RPA calculation of the screened Coulomb electron–electron interaction is performed for the silicon–jellium multilayer model. The superconducting kernel for this multilayered system is found to be positive in the whole frequency range considered. We show that the inclusion of local field ef...
متن کاملQuasiclassical theory of superconductivity : a multiple interface geometry
In many cases of interest such as a multi-layer mesoscopic structure (e.g. a superlattice) or the grain boundaries network in high-T c 's, one deals with the situation where electrons traverses many partially transparent interfaces without loosing coherence. Then, the consequent re-flection/transmission events require a simultaneous consideration. Theoretically, even an isolated interface poses...
