ADDING CLASSES, HOMEWORK REGISTRATION and CREDIT LOCKOUT

If I have issued you a permission number, please enroll asap.

COURSE DESCRIPTION

Building a scanning tunneling microscope from scratch. Operating a STM. Topics covered are applied quantum mechanics, opamp circuits, low-noise electronics, feedback circuits, sample and tip preparation, computer-controlled data acquisition.

TESTS

There is no test

GRADING

At the end of the semester, you are expected to write a report outlining your results. The intended audience for the report is your fellow students who have not yet taken this class. Your grade will be based on

  1. 60 % : Your report
  2. 40 % : Your assignments
  3. Note that this lab is taught together with Dr. Doty. Your final grade will be the average of the grade he gives you and the grade you get from me.

Scores and grades can be contested up to 10 days after they have been published, afterwards they become final.

HOMEWORK

I will give you assignments at the end of class to be completed before next week's class starts.

TENTATIVE CLASS SCHEDULE

This is a public google calendar that is easy to integrate in your own calendar so you will get class changes pushed to your calendar automatically. Use

Your report is due the last day of classes

It has to have the following sections

  1. Introduction to STM
  2. Current amplifier testing and noise characteristics
  3. numerical simulation of STM tip approach + stability (basically the homework)
  4. STM images
    1. analysis of atomic steps + comparison to literature (or STM manual)
      1. STM image
      2. diagram of analysis applied
      3. diagram of expected value
    2. analysis of atomic steps, which involves:
      1. STM image
      2. diagram of analysis applied
      3. diagram of expected value
