The following graphs represent MOSFET transistor band diagrams at two scenarios. E RE Hi Hi H2 - H2 D(E) Scenario 1: MOSFET transistor band diagram 1 D(E) Scenario 2: MOSFET transistor band diagram 2 a. Use your own word to explain the above diagrams. Clearly show the difference between the two scenarios. [10 points) b. Starting from first principles, derive an expression for the measured conductance G in each of the above scenarios. Clearly show the steps that lead to your answer. [15 points) c. Clearly explain why the following statements are correct (use equations to support your answers): - The ballistic conductance does not depend on the channel length L. [5 points) - The diffusive conductance is inversely proportional to the channel length L. (5 points)
