This is an experiment designed to measure the resistance of copper and gold nanowires using a lock-in amplifier.  Students learn:

1. about different types of noise,
2. the principles of phase-sensitive techniques,
3. to extract signals buried in noise using a lock-in amplifier,
4. to operate optical chopper to measure weak optical signals modulated at a certain frequency.
4. to measure the minute resistance of a conducting nanowires.
