Thermal management in large Bi2212 mesas used for terahertz sources
We present a thermal analysis of a patterned mesa on a Bi 2Sr2CaCu2O8 (Bi2212) single crystal that is based on tunneling characteristics of the c-axis stack of ∼800 intrinsic Josephson junctions in the mesa. Despite the ...
Full bulk spin polarization and intrinsic tunnel barriers at the surface of layered manganites
(Nature Publishing Group, 2005-01)
The affect of full bulk spin polarization and intrinsic tunnel barriers on the surface of layered manganites were studied using a combination of surface-sensitive x-ray and tunnelling process. The surface bilayer of ...
Low-field behavior of Ti-added MgB2/Cu superconducting wires
We report on low-field magnetic properties of Ti-added (0-20 wt.% of Ti) Cu-clad MgB2 superconducting wires. Wires were produced by mixing appropriate amount of Ti and reacted MgB2 powder which was then placed inside Cu ...
Counterintuitive consequence of heating in strongly-driven intrinsic junctions of Bi2 Sr2 CaCu2 O 8+δ mesas
(American Physical Society, 2010-06)
Anomalously high and sharp peaks in the conductance of intrinsic Josephson junctions in Bi2 Sr2 CaCu2 O 8+δ (Bi2212) mesas have been commonly interpreted as superconducting energy gaps but here we show they are a result ...
