Area dependence and influence of crystal inhomogeneity on superconducting properties of Bi2212 mesa structures
The rapid increase in applications of terahertz waves requires new techniques to obtain continuous wave terahertz sources. Mesa structures fabricated from high-Tc superconductor Bi2Sr2CaCu2O8+δ (Bi2212) single crystal have ...
Emission of the THz waves from large area mesas of superconducting Bi 2Sr2CaCu2O8+δ by the injection of spin polarized current
Rectangular Au/Co/Au/Bi2Sr2CaCu2O 8+δ (Bi2212) mesa structures with large areas and high thicknesses were fabricated on as-grown Bi2212 single crystals in order to obtain small critical current from as-grown mesas by the ...
The fabrication of THz emitting mesas by reactive ion-beam etching of superconducting Bi2212 with multilayer masks
Generation of powerful THz radiation from intrinsic Josephson Junctions (IJJs) of Bi2Sr2CaCu2O8+δ (Bi2212) may require mesas with large lateral dimensions. However, there are difﬁculties in fabrication of perfect rectangular ...
Effect of magnetic field on quasiparticle branches of intrinsic Josephson junctions with ferromagnetic layer
The interlayer tunneling spectroscopy has been performed on micron-sized mesa arrays of HgBr2 intercalated superconducting Bi2212 single crystals. A ferromagnetic multilayer (Au/Co/Au) is deposited on top of the mesas. The ...
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 ...
