electronic properties of matter
... - The extra electron will not be present in a bond and will thus be able to drift through the material - Example: Si doped with P - The impurity is known as the “Donor” because it donates an extra electron to the crystal lattice p-type material - This is made by doping a semi-conductor with an eleme ...

Nearly Free Electron Approximation
... Can a force be impressed on the electrons to cause them to drift in a particular direction? Below the Fermi level all states are occupied, so there cannot be a net change into any particular direction or particular set of them. So then the material cannot conduct electricity, (no net momentum in a ...

... field thus leading to larger currents. With this definition j=nqv=nq μqE and = nq μq or μq=q/m The two main sources for resistivity are the electron-phonon interaction (interaction with the ions that are hopping in their place) and the interaction with impurities and crystal defects. The former is ...
