Helpful Hints (Matlab scripts, UNIX)

  1. Use the device simulator presented in class to calculate the I-V characteristics of the example submicron MOSFET. Allow Vds and Vgs to range from 0 to 3 volts.

  2. Examine the output at two bias points in detail: a) Vgs=3, Vds=1; b) Vgs=2 and Vds=3. From the graphs of carrier concentration, potential, etc., describe the underlying characteristics of saturation and the linear region of operation.

  3. Experiment with changing the channel length and the source-drain junction depths to determine how they affect the I-V characteristics of the devices.

  4. Extra credit. Describe how you would combine the MOSFET simulations with your Monte Carlo and Boltzmann equation solution to learn more about the device you're simulating.
