Superconductor-insulator-superconductor tunnel junction → Superconducting tunnel junction – I'd like to request that this page be moved to Superconducting tunnel junction, as that title is more concise. Presently Superconducting tunnel junction redirects to this page; I propose reversing the situation. Tls60 (talk) 15:57, 15 August 2011 (UTC)

So what is the difference between a STJ and some other type of Josephson junction?
[edit]Is this not, in some way, an alternate name for the same thing? The article text seems to imply this, or more accurately, fails to describe why it isn't. Maury Markowitz (talk) 12:15, 3 September 2011 (UTC)
A Josephson junction is two superconductors coupled by any type of weak link. The weak link could be a thin insulating barrier, as in the case of an STJ. It could also be a short section of normal (non-superconducting) metal (sometimes called S-N-S), or simply a physical constriction that weakens the superconductivity at the point of contact (sometimes called S-s-S). I tried to make this point clear in the introduction to the article on the Josephson effect, but any suggestions for clarifying this issue in the STJ article are welcome.

It may also be worth mentioning that, while the STJ is a type of Josephson junction, not all the properties of the STJ are described by the Josephson effect. For example, the detector applications are based on quasiparticle tunneling, which is distinct from the Josephson effect. Tls60 (talk) 18:32, 3 September 2011 (UTC)
- Then the intro definitely needs to have this added. Maury Markowitz (talk) 16:15, 4 September 2011 (UTC)
