Title: Josephson junction

Abstract

A novel method for fabricating nanometer geometry electronic devices is described. Such Josephson junctions can be accurately and reproducibly manufactured employing photolithographic and direct write electron beam lithography techniques in combination with aqueous etchants. In particular, a method is described for manufacturing planar Josephson junctions from high temperature superconducting material.

Josephson junction Q-spoiler

Patent Clarke, John [Berkeley, CA]; Hilbert, Claude [Austin, TX]; Hahn, Erwin L [Berkeley, CA]; ...

An automatic Q-spoiler comprising at least one Josephson tunnel junction connected in an LC circuit for flow of resonant current therethrough. When in use in a system for detecting the magnetic resonance of a gyromagnetic particle system, a high energy pulse of high frequency energy irradiating the particle system will cause the critical current through the Josephson tunnel junctions to be exceeded, causing the tunnel junctions to act as resistors and thereby damp the ringing of the high-Q detection circuit after the pulse. When the current has damped to below the critical current, the Josephson tunnel junctions revert to theirmore » « less

High temperature superconductor step-edge Josephson junctions using Ti-Ca-Ba-Cu-O

Patent Ginley, David S [Evergreen, CO]; Hietala, Vincent M [Placitas, NM]; Hohenwarter, Gert K. G. [Madison, WI]; ...

A process for formulating non-hysteretic and hysteretic Josephson junctions using HTS materials which results in junctions having the ability to operate at high temperatures while maintaining high uniformity and quality. The non-hysteretic Josephson junction is formed by step-etching a LaAlO.sub.3 crystal substrate and then depositing a thin film of TlCaBaCuO on the substrate, covering the step, and forming a grain boundary at the step and a subsequent Josephson junction. Once the non-hysteretic junction is formed the next step to form the hysteretic Josephson junction is to add capacitance to the system. In the current embodiment, this is accomplished by addingmore » « less

Superconducting bilayers of two-dimensional materials with integrated Josephson junctions

Patent Lagally, Max G.; Blick, Robert H.

Josephson junctions (JJ) based on bilayers of azimuthally misaligned two-dimensional materials having superconducting states are provided. Also provided are electronic devices and circuits incorporating the JJs as active components and methods of using the electronic devices and circuits. The JJs are formed from bilayers composed of azimuthally misaligned two-dimensional materials having a first superconducting segment and a second superconducting segment separated by a weak-link region that is integrated into the bilayer.

Memory cell comprising coupled Josephson junctions

Patent Braiman, Yehuda; Imam, Neena; Neschke, Brendan

Methods and apparatus are disclosed for operating a memory cell formed from the plurality of coupled Josephson junctions. The memory cell is configured such that applying an electrical signal to the junctions can cause at least one, but not all, of the junctions to change their respective phase states. Subsequent writes to the memory cell using substantially the same electrical pulse do not change the phase state of the plurality of junctions. The memory cell can be ready by providing another electrical pulse to one of the junctions and receiving an output electrical pulse generated in response by a differentmore » « less

Process for direct integration of a thin-film silicon p-n junction diode with a magnetic tunnel junction

Patent Toet, Daniel [Mountain View, CA]; Sigmon, Thomas W [Albuquerque, NM]

A process for direct integration of a thin-film silicon p-n junction diode with a magnetic tunnel junction for use in advanced magnetic random access memory (MRAM) cells for high performance, non-volatile memory arrays. The process is based on pulsed laser processing for the fabrication of vertical polycrystalline silicon electronic device structures, in particular p-n junction diodes, on films of metals deposited onto low temperature-substrates such as ceramics, dielectrics, glass, or polymers. The process preserves underlayers and structures onto which the devices are typically deposited, such as silicon integrated circuits. The process involves the low temperature deposition of at least onemore » « less
