2025年2月5日 · The superconductor is a mixture of organic compounds and that is all i can say so far as you understand..Anyway I checked a voltage across superconductor and it is the same as resistance close to 0, I think I will need a lab to confirm the rest, if any of you can suggest any lab or person capable to do so in close proximity so I can send the ...

2009年12月16日 · However, if make Josephson junctions or SQUIDs out of a d-wave superconductor and orient the electrodes in such as way that you have transport from e.g. a node to a lobe or from a +lobe to a -lobe (known as a pi-junction since this gives an intrinsic pi-shift of the phase) the effects become much more prominent.

2008年5月3日 · The most "obvious" difference between a superconductor and an ideal conductor is that the former expels all magnetic fields when it goes through the superconducting transition. A perfect conductor would just "freeze" the field, but in an ideal superconductor (well, in a type I at least) the field is always zero.

2011年5月19日 · 1. Conventional superconductor: 96% hole superconductors (Chapnik rule). 2. HTSC: hole doped Tc much greater than electron doped Tc 3. Phase diagram of Tc and % of doping: concave, superconductor in a limited region of doping. 4. Homes scaling law: Tc ~ const*(number of superconducting electrons)*(resistivity in normal state)

2008年7月25日 · A superconductor behaves like a perfectly diamagnetic material, suppressing the internal field B because

2010年12月2日 · Getting back to the original question, DrDu is right - there is an upper limit to the current (actually, the current density), and beyond that, the superconductor becomes normal again. However, if you are really talking about a battery, you'll have maybe an …

2014年4月15日 · Power in a superconductor is calculated using the formula P = I^2R, where P is power, I is the current flowing through the superconductor, and R is the resistance of the superconductor. This formula is based on Ohm's law, which states that power is equal to the square of the current multiplied by the resistance.

2015年6月18日 · Hi all, I am currently writing a report about superconductors, and am currently reading about how the band gap shows that single electrons are not the charge carriers responsible for superconductivity. However, I was confused when I read that electrons are fermions and as such there are no band...

2013年7月10日 · According to theory of superconductivity, resistivity almost zero. Below critical temperature the entropy decreases markedly with cooling . why resistivity zero when entropy not equal to zero? my doubt is when there is an entropy there is a disorder. then how can move conducting electron...

2021年5月31日 · Superconductors don’t work that way. There is a critical current density above which the superconductor will suddenly revert to ordinary resistive behavior. As a result there is never any Ohmic voltage across a superconductor. You should calculate ##v## for the critical current density and compare it to ##c##.
