The choices were:
(1) More detail on scaling of traditional semiconductor technology
(2) Alternative structures for smaller transistors (double-gate, SOI,
etc.)
(3) Alternative nano-scale electronic devices (quantum dots, resonant
tunneling diodes, etc.)
(4) Advanced cooling technologies.
(5) Skip this week of the class entirely and move on to the next topic.
The vote was heavily in favor of #3 with a strong contingent for #2 and a few votes for #4. Nobody voted for #1. The decision for the rest of the week was that I would gather information on #3 at least, and #2 if I had time. I ended up not really having time for #2. However some readings were provided on all topics out of #1-4 for those who were interested.
We also passed out an anonymous general survey on the course mechanics
with requests for suggestions for making the class more interactive, etc.
There were some good suggestions: Have an online discussion group, post
student assignments on the web, have student presentations, hold a debate.
I will work out some implementation details, and we'll try out one or more
of these suggestions later in the semester.
