Germanium is an intrinsic semiconductor with eg 0.7 ev. sketch the absorption spectrum for ge (a plot with wavelength on the x axis and % absortion on the y axis). assume that light that is less energetic than the band gap is not absorbed at all (0 % absorption) while light that is more energetic than the band gap is completely absorbed (100% absorption). you must determine and label the critical wavelength for ge (the least energetic wavelength of light that can be absorbed). a. electromagnetic radiation with a frequency of 3.091 x 1014 hz illuminates a crystal of ge. is this light absorbed by the crystal? b. electrons that have been excited to the conductance band of ge can relax to the valence band by photoemission (release of a photon of light). calculate the wavelength of light produced in this emission process. c.
