Influence of Mg Deficiency on the Superconductivity in MgB2 Thin Films Grown by using HPCVD
Ji Young Huh, Won Kyung Seong, Soon-Gil Jung +1
The effects of Mg deficiency in MgB2 films grown by using hybrid physical-chemical vapor deposition were investigated after vacuum annealing at various temperatures. High-quality M…
Growth of Epitaxial MgB2 Thick Films with Columnar Structures by Using HPCVD
Won Kyung Seong, Ji Yeong Huh, Won Nam Kang +4
Epitaxial MgB2 thick films were grown on Al2O3 substrates at 600 oC by using the hybrid physical chemical vapor deposition (HPCVD) technique. In order to obtain a high magnesium va…
Transient Infrared Photoreflectance Study of Superconducting MgB2: Evidence for Multiple Gaps and Interband Scattering
R. P. S. M. Lobo, J. J. Tu, Eun-Mi Choi +4
We studied the far-infrared reflectance of superconducting MgB2 in and out of equilibrium using pulsed synchrotron radiation. The equilibrium data can be described by a single ener…
Interband scattering in MgB2
R. P. S. M. Lobo, M. Elsen, P. Monod +7
The scattering process responsible for connecting the bands remains one of the last open questions on the physical properties of MgB2. Through the analysis of the equilibrium and p…
Critical flux pinning and enhanced upper-critical-field in magnesium diboride films
M. N. Kunchur, C. Wu, D. H. Arcos +5
We have conducted pulsed transport measurements on c-axis oriented magnesium diboride films over the entire relevant ranges of magnetic field $0 \alt H \alt H_{c2}$ (where \hcu is…
Pair-breaking and superconducting state recovery dynamics in MgB2
J. Demsar, R. D. Averitt, A. J. Taylor +5
We present studies of the photoexcited quasiparticle dynamics in MgB2 where, using femtosecond optical techniques, Cooper pair breaking dynamics (PBD) have been temporally resolved…
