a) Drive the Formula for diffusive conductance ? and explain why diffusive conductance depends on the channel length L and cross- sectional area A? [10 marks] b) Draw a plot showing the relationship between diffusive conductance and the channel length L assuming a fixed cross- sectional area A of the conductor. [05 marks] c) Which type of electron transport is more efficient - Ballistic or Diffusive? Justify your answer. [05 marks] d) Design the channel length of a transistor so that 4 out of every 8 electrons reach the drain contact. Assume the material exhibits a diffusion coefficient of 30 cm²/s and average velocity of 105 m/s.
