Why energy level is higher on p side of pn junction diode as compare to n side of same
 
Physics news on Phys.org
Oh no. The justification given in link is not complete. Read it again
 
This is your research project! The article explains the pn junction quite well, and provides a _hint_ for your question in case you have forgotten.

Hint: if the hint given was insufficient for recall, then you can assume that the author has explained it earlier in his lectures ... probably when explaining Fermi levels.
 
Ok. I will read . Thank you
 
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...
