... 1. A superconducting slab occupies the region −d/2 < z < d/2. The region outside this slab is non-superconductor. A magnetic field B0 = B0 x̂ is applied to the superconductor. Thus, the field is B0 just outside the slab on either side. (a). Using the London equations, find the magnetic field everywh ...

... Another important property of charge carriers is their mobility which is defined as μq=v/E where E is the electric field. Carriers with high mobility will pick up speed at small values of electric field thus leading to larger currents. With this definition j=nqv=nq μqE and = nq μq or μq=q/m The tw ...

... current does not change. In this case, drift current is limited not by how fast carriers are swept across the depletion layer, but rather how often. In equilibrium the drift current is limited by the number of minority carriers which are thermally generated within a diffusion length of the junction. ...
