Minimum achievable temperature of ~110 K is measured in a 5% doped Yb:YLF crystal at λ = 1020 nm, corresponding to E4-E5 resonance of Stark manifold. This measurement is in excellent agreement with the laser cooling model and was made possible by employing a novel and sensitive implementation of differential luminescence thermometry using balanced photo-detectors.
2014 In the Bi-Sr-Ca-Cu-O system, we have studied the compound with the ideal formula Bi2Sr2Ca2Cu3O10, responsible for the superconductivity up to 110 K. The magnetic measurements reveal the presence of two phases in the samples with superconducting transitions up to 80 K and 110 K. By varying the composition and the thermal treatment of those samples, we have succeeded in increasing the amount...
It is well-documented that the (111) surfaces of Mo and W are unstable upon the adsorption of ultra-thin overlayers of some fcc metals and transform to {112} type facets. Using first principles total energy calculations, we found that it is also thermodynamically allowed for Mo(111) to facet to the {110} orientations upon the adsorption of a coating layer of Pd and Pt. An overlayer coverage of ...
