Superconducting junction with resonant tunneling [PDF]

open access: yesIEEE Transactions on Magnetics, 1985
In oxide coating metals, localized states exist, which strongly hybridize with conduction electrons forming interface states (IS). This hybridization yields several qualitative and Quantitative new effects typical for oxide coated metals. The Hamiltonians for these new effects describe the: - enhanced coupling of IS to phonons, - strengthened and ...

Current noise in tunnel junctions [PDF]

open access: yesFortschritte der Physik, 2016
We study current fluctuations in tunnel junctions driven by a voltage source. The voltage is applied to the tunneling element via an impedance providing an electromagnetic environment of the junction. We use circuit theory to relate the fluctuations of the current flowing in the leads of the junction with the voltage fluctuations generated by the ...

Ferroelectric Tunneling Junctions for Edge Computing [PDF]

open access: yes2021 IEEE International Symposium on Circuits and Systems (ISCAS), 2021
Ferroelectric tunneling junctions (FTJ) are considered to be the intrinsically most energy efficient memristors. In this work, specific electrical features of ferroelectric hafnium-zirconium oxide based FTJ devices are investigated. Moreover, the impact on the design of FTJ-based circuits for edge computing applications is discussed by means of two ...

Superconducting tunnel junction bolometers [PDF]

open access: yesRevue de Physique Appliquée, 1974
Two new types of superconducting infrared bolometer are described. In one, the temperature dependent Josephson current in an SNS junction is measured with a SQUID galvanometer. In the other, the temperature-dependent quasiparticle tunneling current in an SIN junction is measured with a conventional fet amplifier. Either type of junction is deposited on

Transport in graphene tunnel junctions [PDF]

open access: yesJournal of Applied Physics, 2011
We present a technique to fabricate tunnel junctions between graphene and Al and Cu, with a Si backgate, as well as a simple theory of tunneling between a metal and graphene. We map the differential conductance of our junctions versus probe and backgate voltage, and observe fluctuations in the conductance that are directly related to the graphene ...

Thermal electric effects in Fe|GaAs|Fe tunnel junctions

open access: yesAIP Advances, 2012
We study the spin polarized thermoelectric effects on Fe|GaAs|Fe tunnel junction using a generalized Landauer-Büttiker formalism, where the energy flow is described on the same footing as the electric current.

Tunnel junctions of unconventional superconductors [PDF]

open access: yesPhysical Review B, 1995
The phenomenology of Josephson tunnel junctions between unconventional superconductors is developed further. In contrast to s-wave superconductors, for d-wave superconductors the direction dependence of the tunnel matrix elements that describe the barrier is relevant. We find the full I-V characteristics and comment on the thermodynamical properties of

Simulation of Tunnel Junction in Cascade Solar Cell (GaAs/Ge) Using AMPS-1D [PDF]

open access: yesЖурнал нано- та електронної фізики, 2014
The development of the tunnel junction interconnect was key the first two-terminal monolithic, multi-junction solar cell development. This paper describes simulation for the tunnel junction (GaAs) between top cell (GaAs) and bottom cell (Ge).

Harmonic and reactive behavior of the quasiparticle tunnel current in SIS junctions

open access: yesAIP Advances, 2016
In this paper, we show theoretically and experimentally that the reactive quasiparticle tunnel current of the superconductor tunnel junction could be directly measured at specific bias voltages for the higher harmonics of the quasiparticle tunnel current.
