Spin polarized and degenerate tunneling spectra in intrinsic Josephson junctions of Bi2212
(Wiley-VCH Verlag, 2007)
Tunneling characteristics of HgBr2 intercalated superconducting Bi2212 single crystals have been obtained by using 10×10 μm2 intrinsic Josephson junction stacks, so called mesa structures. The spin degenerate current is ...
Spin polarized current injection through HgBr2 intercalated Bi2212 intrinsic josephson junctions
To investigate the effect of polarized current on tunneling characteristics of intrinsic Josephson junctions (IJJs), spin-polarized and spin-degenerate current have been injected through the c-axis of HgBr2 intercalated ...
Self-heating effect in intrinsic tunneling spectroscopy of HgBr2 intercalated Bi2.1Sr1.4Ca1.5Cu 2O8+δ single crystals
We report tunneling results in intrinsic Josephson junction (IJJ) stacks fabricated in the form of square micromesas on HgBr2 intercalated Bi2.1Sr1.4Ca1.5Cu2O 8+δ (Bi2212) single crystals using photolithography and Ar ion ...
Comparison of intrinsic Josephson and SIS tunneling spectroscopy of Bi 2Sr2CaCu2O8+δ
Tunneling spectroscopy measurements are reported on optimally-doped and overdoped Bi2Sr2Ca2Cu2O 8+δ single crystals. A novel point contact method is used to obtain superconductor-insulator-normal metal (SIN) and SIS break ...
Fabrication of array of mesas on superconducting Bi2Sr 2CaCu2O8+δ single crystals
(National Institute of Optoelectronics, 2005-02)
The superconducting properties of multi-layered high temperature superconductors (HTS) result mainly from the CuO2 planes, while the other structural components behave simply as charge reservoirs. Using these perfect-layered ...
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 ...
