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 ...
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 ...
