SIS[edit]

Thanks for your addition to Sis#Other. Can you clarify -- especially since your description, and the one i suppressed into comments are so similar -- whether "Superconductor-Insulator-Superconductor" and "Superconductor-Isolator-Superconductor" are synonyms, or refer to structures that exploit different phenomena? But still thanks in any case! (Right here on your talk page would be a fine place to reply.)

  • More specifically, it looks like
* Superconductor-Isolator-Superconductor, structure for signal processing using Superconductor Insulator Transitions
* Superconductor-Insulator-Superconductor electronic device used primarily for heterodyne receivers over 100 GHz
should proably be collapsed into
* Superconductor-Insulator-Superconductor, a.k.a. Superconductor-Isolator-Superconductor, electronic device using Superconductor Insulator Transitions
(differing from your wording bcz Heterodyne has no information specific to SIS devices). This would serve to solicit editors to create Superconductor-Insulator-Superconductor (Hmm, renamed from User:Mwengler/Superconductor-Insulator-Superconductor, i hope?) rather than Superconductor-Isolator-Superconductor.
In the event of article creation, i presume we would want to create an Rdr from Superconductor-Isolator-Superconductor, and, assuming i am right that they can be collapsed together, the entry would change to
* Superconductor-Insulator-Superconductor, a.k.a. Superconductor-Isolator-Superconductor, electronic device
since no second article any longer be needed.
(Please forgive me; i know a lot abt Dab stds, but my quantum theory has gotten pretty rusty!)

Superconductor-Insulator-Superconductor and Superconductor-Isolator-Superconductor are indeed synonyms. Both refer to an electronic device which consists of two superconductors separated by a very thing layer of insultating material, often, but not necessarily, and oxide layer of the first superconductor. They are generally manufactured by laying layers of superconducting metals (e.g. niobium, lead) through photolithographic masks, and either putting a very thin layer of a metal to oxidize (eg Al203 in Nb-Al203-Nb junctions) or just oxidizing one of the layers (eg Pb-Pb0-Pb) junctions.

I don't believe EITHER of these terms has any real relationship to the Superconductor Insulator Transition article cited. That refers to long range order in perhaps thin films of superconducting materials, but has no reference to any two-terminal devices such as the SIS. Further, the SIS has SUDDEN transitions in the material realm, and the superconducting states on either side of the insulating barrier are essentially not perturbed from their bulk properties.

I am SLOWLY working on the SIS article which I guess you found at my user page. I should make it a little more about the device before it is ready for prime time. I made it a bit heavy on the application of heterodyne receivers because that is/was my expertise.

But you are right, they are synonyms, but NEITHER of them has any real relationship to the Superconductor Insulator Transition article.

Hi Jerzy,

Assuming you are watching this page and that's why you said I could answer here. I have edited on my user page and now created the article Superconductor-Insulator-Superconductor. Time to take junior to soccer, so I'll let it sit, see if it attracts comment or other notice. I will unless I hear reason not to, probably edit the SIS disambiguation page to combine Superconductor-Isolator-Superconductor with Superconductor-Insulator-Superconductor and remove references to the Superconductor Insulator Transition page.

This is my first article. wikipedia is amazing, I have been using it for years and it just keeps getting better and better. I look forward to feedback and learning how to do this fairly well. Mwengler (talk) 21:57, 24 October 2009 (UTC)[reply]

  • Hope he kicked their butts! You kicked butt IMO on the article, before i could ask more questions. I noted your completion (for however long: "Everything is temporary!) before your new comments above, and have already redone those Sis entries; if my choices are confusing, and you don't feel like diving in the intricacies of MoSDab, i'll be glad to comment and bear in mind that my being wrong is not infrequent (not to mention the times when i'm right, but ...uh, let's call it ... "can't organize support for the correct view". (You may have already read enuf Dab pages to have some grasp, but Dabs are not as simple as probably even most editors assume.)
    I did look at the SI-transition article a little further than a glance, and i see my blatant stupidity in construing "transition" as "interface". [Blush] Thanks for "stopping me before i edit again." I'm a semiconductor guy (i knew slightly the guy who i understand first calculated the minimum surface-state density due to lattice mismatch at the Si/SiO2 interface, and its hard to stop thinking about surfaces.
    Yes, amazing; i'm a Charlie Rose fan, and love to quote Eric Schmidt: "a great accomplishment of humanity". It's a lot of work, and AFAI can see low-efficiency, but IMO it's well worth doing ... for those who turn out to want to continue doing so. And hurrah for those who sit down and write a whole article, as i seldom do; it's pretty hard to get decent prose by just accumulated effort of tinkerers. Thanks for wanting to start, and hope you continue to find it worthwhile.
    Oh, and below is your standard welcome.

    • Just scanned thru your contribs page, and should add thanks for not giving up when your first addn to the Dab page apparently disappeared. And FWIW, where you started that work was on a user sub-page that belongs to you (so far your only one); some colleagues who haven't encountered one would stare at your user page wonder what you meant, and perhaps resort to examining its edit history.
