Superconducting thin-films
Through my work on SNSPDs, I came across some need to characterize superconducting thin-films. There are better resources on the internet, but sometimes I just need to look up something.
| $\rho_0(T)$ | Specific resistivity |
| RRR | Residual-resistivity ratio (RRR), $R(T=RT) / R(T \approx T_C)$ |
Coherence Length
| \[ \xi(T=0K) = \sqrt{\frac{\Phi_0}{2 \pi B_{C2}(T=0K)}} \] |
Magnetic field penetration depth
| \[ \lambda(T=0K) = \sqrt{\frac{\hbar \rho_0}{\pi \mu_0 \Delta(T=0K)}} \] | |
Depairing current
