In your writeup please address the answer the following questions:

• What is the difference between passive and active devices?
• List the different kinds of molecular devices. Describe their analog to a CMOS device and the primary physical mechanism they use to achieve their behavior.
• How does assembly change the devices?
• How do molecular tranistors (e.g., Carbon nanotubes or cobalt complexes) differ from MOSFETs?
  • What is the mechanism that makes a carbon nanotube (CNT) behave like a transistor?
  • Is there subthreshold leakage? Why/Why not?
  • Compare the performance of a CNT to a MOSFET.
• List three reasons why a CNT-transistor might be hard to use in real circuits.
• What is the main difference between a molecular device and a CMOS device.
