Are Semiconductors Electrically Charged?

AI Thread Summary
Semiconductors, including n-type semiconductors, are not electrically charged despite containing excess electrons. The doping process involves adding neutral atoms, which introduce extra electrons into the conduction band without creating an overall charge. The presence of these excess electrons is balanced by the positive charge of the dopant atoms' nuclei. Therefore, while n-type semiconductors have more electrons, they remain electrically neutral. Understanding this balance is crucial for grasping semiconductor behavior.

are semiconductors charged? i mean '"n" type contains excess of electrons, so they should be charged...
please tell me where i am wrong
tks for any answer...

Doped semiconductors are not charged. We dope the material with neutral atoms, not ions. The excess carriers are due to unbonded electrons or desired bonds with the atoms.

Nope, they are not charged. Excess electrons are there because dopants, like phosphorus, gives extra electron to conducting band (per atom), but don't forget that same phosphorus atom has extra positive charge in nucleus so it evens out.
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
