Question:
Plasma frequency and electrical conductivity an organic conductor has been found by optical studies to have wp = 1.80 x 1015 s-1 for the plasma frequency, and τ = 2.83 x 10-15 s for the electron relaxation time at room temperature.
(a) Calculate the electrical conductivity from these data. The carrier mass is not known and is not needed here. Take ε(∞) = 1. Convert the result to units (Ω cm)–1.
(b) From the crystal and chemical structure, the conduction electron concentration is 4.7 x 1021 cm–3 Calculate the electron effective mass m.
