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 ...
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 ...
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 ...
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 ...
