Thermally induced 0-pi phase transition in Josephson junctions through a ferromagnetic oxide film
Thermally induced 0-pi phase transition Josephson junctions through ferromagnetic oxide film
2010/11/9
We investigate the Josephson transport through a ferromagnetic oxide film, e.g., La$_2$BaCuO$_5$, theoretically. Using the recursive Green's function technique, we found the formation of a pi-junction...
Critical State Models for Intergrain Junctions of Polycrystalline Superconductors by Third Harmonic ac Susceptibility Measurements
Low field Josephson junction Critical state models
2010/4/9
High harmonic response of high-Tc and Chevrel-phase polycrystalline superconductors are measured in the presence of small ac excitation field and dc magnetic field applied on it. The aim of this work ...
Carbon Nanotube Structures: Y-Junctions and Nanorings
Carbon Nanotube Structures Y-Junctions Nanorings
2010/10/21
The possibility of coupling two Y-junctions of carbon nanotubes, forming a type of nanotube ring is addressed here. Recent experimental evidences of growing carbon nanotube structures forming basicall...
Barrier Heights of Antimony / and Bismuth / P -Silcon (100) Junctions
Barrier Heights Antimony Bismuth P -Silcon (100) Junctions
2010/4/15
Junctions were fabricated in vacuum of about 10-5 Torr by thermal evaporation of Sb or Bi onto chemically etched p-type silicon (100) substrates. The electrical properties were studied by current volt...
