Fano resonance in Raman scattering of graphene
Duhee Yoon, Dongchan Jeong, Hu-Jong Lee +4
Fano resonances and their strong doping dependence are observed in Raman scattering of single-layer graphene (SLG). As the Fermi level is varied by a back-gate bias, the Raman G ba…
Two-gap and paramagnetic pair-breaking effects on upper critical field of SmFeAsO and SmFeAsOF single crystals
Hyun-Sook Lee, Marek Bartkowiak, Jae-Hyun Park +7
We investigated the temperature dependence of the upper critical field [] of fluorine-free SmFeAsO and fluorine-doped SmFeAsOF single crystals b…
High-pressure growth of fluorine-free SmFeAsO superconducting single crystals
Hyun-Sook Lee, Jae-Hyun Park, Jae-Yeap Lee +6
Superconducting single crystals of SmFeAsO without fluorine doping were grown at a pressure of 3.3 GPa and a temperature of 1350-1450 C by using the self-flux metho…
Spin relaxation in mesoscopic superconducting Al wires
Yun-Sok Shin, Hu-Jong Lee, Hyun-Woo Lee
We studied the diffusion and the relaxation of the polarized quasiparticle spins in superconductors. To that end, quasiparticles of polarized spins were injected through an interfa…
Microwave-induced constant voltage steps in surface junctions of Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} single crystals
Yong-Joo Doh, Jinhee Kim, Kyu-Tae Kim +1
We have observed the zero-crossing steps in a surface junction of a mesa structure micro-fabricated on the surface of a Bi-2212 single crystal. With the application of microwave of…
