460: Introduction to TEM

Description

The primary focus of this course is to provide both the fundamental theory as well as hands on practice with the use of transmission electron microscopy to study the structure of solids. Please note that there will be no coverage of scanning electron microscopy (SEM).

There are no prerequisites for this class beyond a basic knowledge of solid structures and typical defects. If you are not a Materials Science major, and have not had any prior exposure, I would strongly suggest that you borrow from the library an introductory text on materials science which explains about dislocations, grains, and a little about crystal structure.

    Lab Outline | Lab Schedule

    The labs are 2 hours per week, hands on use of the TEM. You have to take the labs if you want a grade. If you are auditing the class, you will have to either get your advisor to pay for the cost of the labs (about $1200) or your Department. The schedule for the labs will be determined in class. The first lab will be a general safety tour and introduction which will take about 1 hr, and we will meet in the EPIC facility in Tech.

    Notes for Lab Reports.

    Lab reports are due Friday at 5 PM the week after you do the lab by email to the TA.
