... Electron band diagrams are a way to visualize what happens at a p-n junction, using the following rules: 1. The Fermi level must be at the same level on both sides of the junction when there is no applied field 2. Far from the junctions, the materials inherent electrical structure exists 3. He band ...

... An electric field is the property of space by means of which one electrically charged particle exerts a force on another electrically-charged particle. The charge of particle 1 changes the space around it, giving it the property we call the electric field. The electric field of particle 1 exerts a f ...

This is due to the interaction between the external field and the B field produced by the orbital motion of the electron. Only certain angles are allowed between the orbital angular momentum and the external magne ...

Bohr–Einstein debates
The Bohr–Einstein debates were a series of public disputes about quantum mechanics between Albert Einstein and Niels Bohr. Their debates are remembered because of their importance to the philosophy of science. An account of the debates was written by Bohr in an article titled ""Discussions with Einsteinon Epistemological Problems in Atomic Physics"". Despite their differences of opinion regarding quantum mechanics, Bohr and Einstein had a mutual admiration that was to last the rest of their lives.The debates represent one of the highest points of scientific research in the first half of the twentieth century because it called attention to an element of quantum theory, quantum non-locality, which is absolutely central to our modern understanding of the physical world. The consensus view of professional physicists has been that Bohr proved victorious, and definitively established the fundamental probabilistic character of quantum measurement.
