Hello Every body!

As shown in below, If i join a heavily doped n+ semiconductor with an ordinary n-type semiconductor,

What is the type of contact that forms between n+and n-type semiconductors ?
is it Ohmic contact or rectifying contact ??
 
it's Ohmic.
 

Thread 'Stability of persistent currents in superconductors regardless of temperature'

From the BCS theory of superconductivity is well known that the superfluid density smoothly decreases with increasing temperature. Annihilated superfluid carriers become normal and lose their momenta on lattice atoms. So if we induce a persistent supercurrent in a ring below Tc and after that slowly increase the temperature, we must observe a decrease in the actual supercurrent, because the density of electron pairs and total supercurrent momentum decrease. However, this supercurrent...

Thread 'Instantaneous dipole moment and orbitals'

Hi. I have got question as in title. How can idea of instantaneous dipole moment for atoms like, for example hydrogen be consistent with idea of orbitals? At my level of knowledge London dispersion forces are derived taking into account Bohr model of atom. But we know today that this model is not correct. If it would be correct I understand that at each time electron is at some point at radius at some angle and there is dipole moment at this time from nucleus to electron at orbit. But how...
