P-type semi conducting material is Select one: a. holes are majority charge carriers and it is due to addition of trivalent impurities. O b. electrons are majority charge carriers and it is due to addition of trivalent impurities. O c. holes are minority charge carriers and it is due to addition of pentavalent impurities. Od. electrons are majority charge carriers and it is due to addition of pentavalent impurities.
Consider a conductor. If one of the terminals is subject to a higher potential while the other terminal to a lower potential, which of the following happens? The free electrons in the conductor will move and concentrate on the side with higher potential. The free electrons in the conductor will move and concentrate on the side with lower potential. The valence electrons will be dislodged from their parent atoms and move in random directions in the conductor. The answer cannot be found on the other choices.
1. An electron moving in a conjugated bond framework can be viewed as a particle in a box. An externally applied electric field of strength & interacts with the electron in a fashion described by the perturbation: V(r) = ee (x - 1) Where x is the position of the electron in the box, e is the electron charge, and Lis the length of the box. (a) Compute the first order correction to the energy (b) The first order correction to the wave-function (compute only the contribution to Y made by Y2)
