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 ...
Terahertz wave emission from layered superconductors: Interferometer measurements
Rectangular Bi2Sr2CaCu2O 8+δ (Bi2212) mesa structures were fabricated on as-grown Bi2212 single crystal superconductors using standard photolithography and Ar ion beam etching techniques. We have performed c-axis resistance ...
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 ...
Terahertz wave emission from intrinsic Josephson junctions in high- Tc superconductors
(IOP Publishing, 2009)
Recently, we experimentally demonstrated that rectangular mesa structures of intrinsic Josephson junctions (IJJ) in Bi2Sr2CaCu 2O8+d (Bi2212) can be used as a compact solid-state generator of continuous, coherent and ...
