متن کاملJosephson effect in small - area superconducting tunnel junctions at 604
We have measured the ac Josephson effect in small-area superconducting tunnel junctions at 604 GHz (A = 496pm) using a resonant planar dipole antenna to couple the radiation into the junction. In a 176-fl junction, we have observed up to the 7th Josephson step (at 8.75 m V), a performance comparable to that seen in point contacts. We also compare our data with the results of the RSJ model and o...
متن کاملDistributed readout detectors using superconducting tunnel junctions
Superconducting tunnel junctions (STJs) are able to measure the energy of single photons in the range from near infrared to X-rays. They provide simultaneous information of the impact time and wavelength of an absorbed photon. The main difficulty of these detectors compared with conventional imaging detectors lies in their limited pixel number. Each STJ has to be connected independently and the...
متن کاملTHE PHONON SPECTRUM EMITTED BY SUPERCONDUCTING Sn TUNNEL JUNCTIONS
The phonon spectra emitted by superconducting tunnel junctions were directly analyzed with high resolution using tunable acceptor states of B in Si as a spectrometer. A consistent and detailed experimental picture of the different parts of the spectra under various injection conditions was obtained for the first time. Tunnel injection of electrons into superconductors leads to energetic quasipa...
متن کاملStrong Approximation of Brownian Motion
Simple random walk and Brownian motion are two strongly interconnected mathematical concepts. They are widely involved in not only pure math, but also in many other scientific fields. In this paper I will first introduce and define some basic concepts of discrete-time random walk. Then I will construct Brownian Motion with some basic properties, and use a method called the strong approximation ...
