A semiconductor has an intrinsic charge carrier density of 1×1014cm3 ,a charge carrier lifetime of 10us, an electron diffusion coefficient of 36 cm2/s, and a hole diffusion coefficient of 12cm2/s. It is at a temperature of 450K and is illuminated by a laser beam at an optical generation rate of 1019 electron‐hole‐pairs/(cm3∙s) What is the separation between the electron and hole quasi‐Fermi levels? Show these quasi‐Fermi levels on a rough sketch of the energy band diagram with the intrinsic, conduction...

For a 3D free electron gas, derive expressions for the Fermi momentum, Fermi energy, and density of levels. Then plot the density of levels and contrast its behavior as a function of energy. Your answers should be expressed in terms of the electron concentration n = N / V and some combination of fundamental constants.

Use the Fermi energy plus the neutron separation energy to estimate the depth of the potential well for Fe^56 (A=56, Z=26) What I understand so far: The depth of the well --> |Vo| = (Fermi energy) + (Neutron separation energy) Where the neutron separation energy is the binding energy of the last neutron (Would this be the same as the B.E per nucleon usually use to find the plot of the binding fraction? ) Please detail every step you make....
