Dome-shape superconductivity phase diagram can commonly be observed in cuprateand iron-based systems via tuning parameters such as charge carrier doping, pressure, bond angle, and etc. We report doping electrons from transition-metal elements (TM = Co, Ni) substitution can induce high-Tc superconductivity around 35 K in Ca0.94La0.06Fe2As2, which emerges abruptly before the total suppression of ...
An array of Ag nanoboxes fabricated by helium-ion lithography is used to demonstrate plasmon-enhanced nonradiative energy transfer in a hybrid quantum well-quantum dot structure. The nonradiative energy transfer, from an InGaN/GaN quantum well to CdSe/ZnS nanocrystal quantum dots embedded in an ~80 nm layer of PMMA, is investigated over a range of carrier densities within the quantum well. The ...
By developing a general framework for transport across superconducting junctions that goes beyond the standard Andreev approximation, two crucial signatures are proposed $s$-wave Josephson along BCS-BEC crossover: negative differential conductance as signature of unitarity and complete suppression multiple-Andreev-reflection-induced current hallmark splitting point.
