Question
I. True or False (5%) ial well with infinite potential In the particle in the box problem where a particle is in a potenti a. at the boundaries, the energy of the particle increases with decreasing well width. b. In quantum numbers (n, I, m), the following triplet is valid (4, 2,-2) c.Effective mass of a material can be determined by the curvature of the E-k diagram d. In an indieet semiconductor, the majority of recombination occur via recombination levels e. At thermal equilibrium, the generation and recombination of ehp are equal in an intrinsic material f. A p-n junction has a variable capacitance depending on bias. g. In a depletion mode MOSFET the channel is created by implantation of ions not gate bias h. Diffusion capacitance is zero if the diode length is longer than the diffusion length. i. The field effect allows for the modulation ofa material's camer concentration j. The momentum relaxation time is the average time between scattering events. k. We can accurately predict the energy and time of an electron. 1. Carrier mobility does not depend on temperature m. In a direcet bandgap material, recombination of carriers results in the generation of a phonon. n. Avalanche breakdown occurs if the potential barrier is narrow, allowing for tunneling of carriers o. For an Schotky contact there is a higher concentration of majority carriers at the interface p. Current can flow between source and drain with a gate bias, Vo-0 in an enhancement mode MOSFET Max depletion width of a MOS structure occurs during accumulation q. The Hall effect is used to measure the minority carrier concentration and mobility due to the induced Lorentz force on the carriers with applied current and magnetic field. Common Base (BJT) is commonly used as a current amplifier The Early Eft r ses a decrease in le with increased Vic as the depletion region from the ollector extends significantly into the base.Explanation / Answer
