Planar superconductor-normal-superconductor Josephson junctions in MgB2 [PDF]
Applied Physics Letters, 2001 We report the successful creation of planar MgB2 junctions by localized ion damage in thin (100 nm) films of MgB2 on sapphire by milling a 50 nm trench with a focused-ion beam across tracks of widths between 1 and 5 μm. When the depth of the trench is between 70% and 80% of the film thickness, devices show critical currents (IC) for temperatures below ...

The pressure dependence of the critical temperature of MgB2 [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2021 The dependence of the critical temperature Tc on the pressure P in the magnesium diboride MgB2 has been studied in the two-band model. In each band consists of two pairing interaction, electron-phonon interaction and non-electron-phonon interaction ...
