Noise characteristics and detectivity of YBa2Cu3O7 superconducting bolometers: Bias current, frequency, and temperature dependence
Meander line patterned infrared detectors, with values of resistance Ronset at the onset temperature Tc onset of 3–5 kV, were fabricated from YBa2Cu3O72x superconducting material on MgO and SrTiO3 crystalline substrates. Noise voltages from the samples were measured versus bias current, radiation modulation frequency, and temperature, in both the normal and superconducting states. Four major ty...
متن کاملTemperature dependence of critical currents and ac transport losses in (Bi,Pb)2Sr2Ca2Cu3Ox and YBa2Cu3Oy tapes
The critical currents and self-field ac losses of YBa2Cu3Oy coated conductors and (Bi, Pb)2Sr2Ca2Cu3Ox tapes were measured at several temperatures between 45 K and the respective critical temperature. The temperature dependence of ac losses was measured at 50 Hz using the lock-in method for a transport current. The frequency dependence of ac loss was measured at 55 K for transport current frequ...
متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...

Critical Temperature Dependence of High Frequency Electron Dynamics in Superconducting Hot-Electron Bolometer Mixers Irfan Siddiqi May, 2002 Superconducting diffusion-cooled hot-electron bolometer (HEB) mixers are ideal candidates for use in terahertz heterodyne spectroscopy (THz). This thesis investigates mixer performance as a function of the superconducting transition temperature (Tc). In th...
متن کاملOBSERVATION OF NONUNIFORM CURRENT TRANSPORT IN EPITAXIAL YBa2Cu3O7– x FILM NEAR THE SUPERCONDUCTING TRANSITION TEMPERATURE
We have studied the local transport properties in an epitaxial YBa2Cu3O7 x (YBCO) film on LaAlO3 (LAO) using variable temperature scanning laser microscope (VTSLM) near the superconducting transition. A map of the superconducting transition temperature ðT c Þ is generated from a series of VTSLM images. The map of T c indicates there are inhomogeneities in the film large enough to create nonunif...
