Transmission Electron Microscopy & Its Practical Applications
- Fall '99
Proposed boilerplate for Physics 308 -
Transmission Electron Microscopy (3)
Prerequisite: Physics 307 and/or consent of instructor. A
lecture/laboratory study of transmission electron microscopy
(TEM) in conventional, analytical, and phase-contrast (high
resolution) applications. Course includes advanced electron
optics and image formation, defect structures, specimen
preparation, contrast theory, diffraction/periodicity analysis,
and electron energy loss/x-ray spectroscopy. Two hours lecture
and two hours laboratory per week.
You might also think of this as a course in Trans-nano Electron-assisted self-Miniaturization. A web-quiz on lattice and reciprocal lattice indexing can be found here.
This course is geared towards training students to effectively use a TEM and its various accoutrements for the analysis of electron scattering and x-ray generation by specimens. The theory part will cover the basic physics of Transmission Electron Microscopy, so that information obtainable from specimens is understood. The lab part deals with operation of such instruments, including a computer-controlled Hitachi H600 TEM and an atomic-resolution Philips EM430 SuperTwin AEM in our lab. Some prior experience with electron microscopes (e.g. via the scanning electron microscope, offered in the fall) is recommended.

To take the course, apply to enroll by e-mail or in person with the course instructors. The first class meeting will likely be from 9am to 11am on Saturday, August 28, 1999 in Molecular 101. Stop in to participate in the discussion if for no other reason!
The course in 1999 will will be taught primarily by Prof. Jimmy Liu at Monsanto (before that John Cowley's group at Arizona State University). We have two operating TEM's (including a million dollar instrument under $30K/yr service contract which can resolve atoms) available for the course, as well as two SEM's, and some scanning probe microscopes in a triple bi-story building designed for such instruments from the ground up.
Newsflash: As a non-traditional course offering, available on weekends to minimize conflict with other courses or "day jobs" (and with no supported mandate or time for the instructors to go out and spread the word in advance) we have traditionally discussed enrollment with prospective students during the first week of classes. As a course which is worth (in employment attractiveness alone) easily worth three times the tuition cost on the open market, it is not hard to fill up the seats. This semester, the evening college dean decided to close the course before anyone could enroll! We are currently assessing whether or not to reopen enrollment this semester, or to simply teach the course next winter. If you have opinions on this, let me know (pfraundorf@umsl.edu), or stop by this Saturday morning (9am Molecular 101 28 Aug 1999) to discuss.

A note
on cross-sections and mean-free-paths to clarify Chapter 2 of
Williams/Carter. This course has begun. Draft description of a
possible summer workshop series targeted toward analytical
service clients rather than operators. Schematic on the
focussing effect of magnetic lenses. This course now has a university-wizarded webpage
and discussion
area. Ask in class for the discussion password if you don't
have it. The pre-course login ID is [Physcs308.001],
while the pre-course password is [Physcs308.001]
Questions this course might help you answer... Why image with electrons rather than light? From the vantage point of a micro-human, spiders look like... What about micro and nano-worlds can a scanning electron microscope tell? Why image with secondary rather than primary electrons? What happens when a 20,000 volt electron encounters a penny? How accurately may grain-size and RMS roughness be measured here? What knob should I turn next? Do flea-whiskers have whiskers? What determines the resolution of an image?

electron microscope image on-line! deBroglie's electrons

making a hotdog require 50 nanoseconds of life's power

physics a dead subject, or is there another
paradigm change afoot? What other resources might help you?
