Due to collisions with the surface of one of these materials, an important reduction in mobility occurs in inversion layers.
Due to collisions with the surface of one of these materials, an important reduction in mobility occurs in inversion layers. If a minimum does not occur at the origin of an E-k plot for these materials, phonons must participate in radiative transitions, making them indirect. These materials are degenerate when a difference of less than 3kT exists between the conduction band and the Fermi level. They can be compensated if there are an equal number of donors and acceptors. These materials are classified as extrinsic when doped. For 10 points, identify these materials with intermediate conductivity that include silicon and germanium.
