Amorphous selenium (a-Se) is a high resistivity semiconductor that has a density of approximately 4.3 g cm-3 and an atomic number and mass of 34 and 78.96, respectively. Its relative permittivity at 1 kHz has been measured to be 6.7 Calculate the relative magnitude of the local field in a-Se. Calculate the polarizability per Se atom in the structure. What type of polarization is this? How will εr depend on the frequency?
