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 ...
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 ...
