Superconducting Transition in Electron-Doped 12CaO 7Al2O3
It was reported that a mixed light metal oxide compound, 12CaO 7Al2O3 (C12A7), which is known as a constituent of aluminous cement, became a superconductor at an ambient pressure by the exclusive replacement of extra-framework oxygen ions in subnanometer-sized crystallographic cages with electrons. Temperature dependences of resistivity, magnetic susceptibility, and magnetic field dependent res...
متن کاملVUV and cathodoluminescence spectroscopy of 12CaO 7Al2O3
Reflection, photoand cathodoluminescence of 12CaO 7Al2O3 (C12A7) were investigated. Smooth features observed in VUV reflection spectrum of monocrystalline C12A7 evidence its complicated crystalline structure and lattice disorder. Two luminescence bands peaking at 4.9 and 3.35 eV were revealed in C12A7 ceramics having encaged electrons and O ions. The 4.9 eV emission has an excitation onset at 6...
متن کاملHopping versus bulk conductivity in transparent oxides: 12CaO·7Al2O3
First-principles calculations of the mayenite-based oxide, fCa12Al14O32gs2ed, reveal the mechanism responsible for its high conductivity. A detailed comparison of the electronic and optical properties of this material with those of the recently discovered transparent conducting oxide, H-doped UV-activated Ca12Al14O33, allowed us to conclude that the enhanced conductivity in fCa12Al14O32gs2ed is...
