Pressure effects on the superconducting thin film BaKFeAs
Eunsung Park, Nam Hoon Lee, Won Nam Kang +1
We report electrical resistivity measurements on a high-quality BaKFeAs thin film () under pressure. The superconducting transition temperature (=3…
Perfect Domain-Lattice Matching Between MgB2 and Al2O3: Single-Crystal MgB2 Thin Films Grown on Sapphire
Won Kyung Seong, Sangjun Oh, Won Nam Kang*
We have found that single-crystal films can be grown on (0001) Al2O3 substrates through the golden relation of a perfect lattice-matching ratio between the a-axis lattice constants…
Fabrication of FeSe1-x superconducting films with bulk properties
Soon-Gil Jung, Nam Hoon Lee, Eun-Mi Choi +4
We have fabricated high-quality FeSe1-x superconducting films with a bulk Tc of 11-12 K on different substrates, Al2O3(0001), SrTiO3(100), MgO(100), and LaAlO3(100), by using a pul…
Potassium-doped BaFe2As2 superconducting thin films with a transition temperature of 40 K
Nam Hoon Lee, Soon-Gil Jung, Dong Ho Kim +1
We report the growth of potassium-doped BaFe2As2 thin films, where the major charge carriers are holes, on Al2O3 (0001) and LaAlO3 (001) substrates by using an ex-situ pulsed laser…
In-situ fabrication of cobalt-doped SrFe2As2 thin films by using pulsed laser deposition with excimer laser
Eun-Mi Choi, Soon-Gil Jung, Nam Hoon Lee +6
The remarkably high superconducting transition temperature and upper critical field of iron(Fe)-based layered superconductors, despite ferromagnetic material base, open the prospec…
