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 ...
Investigation of the tunneling spectra in HgBr2-intercalated Bi-2212 single crystals below and above Tc
Interlayer tunneling spectroscopy measurements were performed on mesa arrays of Bi-2212 single crystals, intercalated with HgBr2. Tunneling conductances were obtained over a wide temperature range to examine the spectral ...
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 ...
Reply to "comment on 'Counterintuitive consequence of heating in strongly-driven intrinsic junctions of Bi 2Sr 2CaCu 2O 8+δ mesas'"
(American Physical Society, 2011-10)
The main criticism raised in the preceding Comment concerns our suggestion that sharp conduction peaks in Bi 2Sr 2CaCu 2O 8+δ mesas, along with absent dip-hump features, may, in general, be a result of self-heating. The ...
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 ...
