I think it is Newton's first law , because its statement itself says that until we apply an external force, a body continues to be in its original state of rest or of unifrm motion in straight line. But one of my colleagues thinks that it is the third law, because action reaction forces are...

Conservation of linear momentum is consequence of which one of Newton's three laws?

in case of compton effect,elastic collision between x-ray photon and target electron takes place. The electron close to the nucleus of the atoms are tightly bound. When such bound electrons scatter x-rays,the collision is considered to be taking place between the photon and the whole atom. the...

:confused: why can't wave nature of light explain photoelectric effect?

but I thought ,Marcus, that SC band bends downwards for N type and upwards for Ptype ?!

I've read about schottky diode that , such a metal-semiconductor combination is taken in which Ef of metal lies between the bottom of conduction band and top of valence band of the semiconductor. Why is it so?

well i don't know the complete answer but i just know that in case of denerate N type semiconductor , fermi level moves into the conduction band. While in case of P type semiconductor it moves into valence band.

in books we have read that there lies a forbidden gap between conduction band and valence band. and electrons can not exist in this gap i.e. probability of electron being found in this region should be zero. BUT the fermi level,which has 50% prabality to contain an electron is found in...
